It still costs money. More asphalt, more padding = more cost, more labor to put it in. If you don't have to put it in, that saves you money to keep up with the luxury models, which was my only point.

Roughly speaking, when you go to make an EV, you want an efficient motor to better conserve battery power. A more efficient motor can also be used as a more efficient generator when you're doing regenerative braking. One thing about electric motors is that larger, more powerful ones are also more efficient. So when you use a very efficient motor you end up with power levels that can run a luxury performance vehicle.

Now consider long range - batteries are not only limited by the amount of energy they contain, but the amount of power they can provide(IE energy over time). Longer range = more batteries, which also equals more power - indeed, more than enough to run that bigger, more efficient and powerful electric motor at it's full potential. So we're back to luxury performance vehicle levels of power.

As an aside, back in the day auto companies that make hybrids did a lot of research into increasing the power capacity of their batteries so they could put a smaller, shorter ranged battery in. Regenerative braking was seriously limited by the power absorption capabilities of the battery. With a long range EV? Not so much.

But Li-Ion batteries are pushed much harder. If a battery needs replacement, you lose about half of the original cost of the car at that very instant.

With a Leaf, maybe. Tesla warranties their batteries for 8 years/125k miles.

They're on record saying that they expect their 60 kwh pack to last at least 200k miles, and you can pre-purchase a new 60kwh battery pack replacement in 8 years for $10k today.

Batteries can be damaged by full charge and by low charge, so we have to see how it plays out IRL. Traditional cars aren't going to need any such service after only 75K miles. After 150K - maybe. But then an EV would surely be on its second, if not third, battery pack.

Not from what I'm seeing. At 150k there's a chance it'll be on it's 2nd. In addition, Different battery chemistries have different behaviors, characteristics, and quirks. Still, consider that when you have a multi-thousand dollar battery you're not just clamping any old charge system to it. They're carefully mated for optimal performance and lifespan.

For example, from what I've read, '100%' charge for the common EV's is actually only 90% of the battery's capacity, which reduces battery degradation substantially, and we've come a long way in LiIon manufacturing. With long range EV's, the battery pack actually ends up so huge that even a 'fast charge' is more like a normal charge for smaller battery packs. A fast charge for a NiMH cell is something like 10 minutes, and will cause problems with heat and such. An equivalent 'fast charge' for an EV takes over an hour even with a special fast charge station due to the sheer size of the battery pack.

With regard to noise, a lot of that insulation also dampens road noise - which is not going to be any lower, until you switch to antigravity. So you probably still need a lot of that foam and rubber.

As Rioki mentioned, it's been my perception that motor noise has always overpowered road noise, especially at higher speeds, as the engine power necessary to maintain a given speed to goes up exponentially as your speed increases due to wind resistance.

Makes me wish I had my spreadsheet handy. Still...
$20k Camry vs $30k Tesla BlueStar.
Price difference: $10k.

Assumptions: $4 gasoline, $.10 kwh, 15k miles/year, .3 kwh per mile(Leaf, Roadster, and Model S are all close to this). I'm also assuming the routine maintenance difference(~$600/year for oil/filters/brakes/belts/plugs/etc...) is balanced out by maybe needing to replace the battery.

The Camry is listed as 25/35. If you drive mostly highway and would get 35 with the Camery, you'll use 429 gallons a year, and the EV would save you $1,264 a year in fuel costs alone. More if you can get free charging somewhere, like at work. Still, you're looking at just shy of 8 years to break even(car is expected to last twice that, but odds of needing a new battery go up) If you're a nasty city driver, you're closer to $2k, and you should 'break even' just after 5 years.

If gasoline goes to $5/gallon, you break even at 6 and 4 years, respectively.

One of the 'tricks' with electric cars that make them 'better' suited for the luxury market is that more powerful motors tend to be more efficient - despite being far heavier and more powerful, the shorter ranged model S effectively uses the same amount of electricity per mile. In other words, put in an engine powerful enough for luxury sedans and you also get great efficiency. You also have the potential for smooth acceleration, no shudder, no gas fumes, no needing to pull into smelly stations for a fillup, etc... It's cheaper(and more profitable) at this time to 'finish' dolling the vehicles up and sell them to rich people. That helps pay a startup to continue developing a truly economical vehicle.

Consider how much effort goes into a luxury sedan to make sure the engine's vibrations and noise(beyond a carefully selected amount) don't make it to the passengers. No real need with an EV, so there's some money saved to allow it to compete with the expensive vehicles. They don't worry about it that much with a Camry level vehicle.

California requires that I own a lock and/or safe which was purchased at the same time as the weapon

Yeah, it's crazy, I mean, I haven't filled my 30 gun safe yet. Most handgun safes hold at least 2-3 weapons. Why force me to buy a lock I'm not going to use because I have a perfectly functional safe at home?

Some of the dealerships I'm at have 'free' cable/trigger locks in a basket. It's up to you whether you take one or not. BTW, I know one guy who uses the cable lock that came with his gun on his gym locker...

Seems to me like most modern 1911 triggers have holes in them.

Mine's a milspec, no holes. A google search of 37 images for "1911" that is actually of a 1911 with the trigger exposed gave me 20 with holes, 17 without. Almost even. Even then, I wouldn't rate all of the holes as suitable for either putting a padlock through, or even if you can get a padlock into the hole, that it would restrain the trigger enough to prevent discharge.

For example, this image has the holes rather far forward...

The lock is for pure child safety. I prefer a safe.

But that is probably exactly what lawmakers want. Since they cannot ban guns outright, make them cost prohibitive to the average person. It's bad enoguh the ones I want are $500 plus. Add in Bio and it's a possible extra $200...

That's exactly what they want. Add $200 to the price of the gun. 20% to the price of ammo. $20 annual registration fee. Make it expensive and a pain to keep legal.

Back in the day there were laws mandating metals with higher melting points and such in order to try to keep 'saturday night specials' off the streets. To be fair, those are actually the weapons most often used in crimes - $2k AR-15s are used in crime extremely rarely. The most common are cheap revolvers/semis in .22 to around .380.

In my life they always seem to go after the wrong guns- The brady bill, the original AWB, targeted rifles in the name of a man harmed by a .22lr six shot revolver. The only things that would have made a difference was that he couldn't have used the gimmicky 'exploding' bullets that don't actually explode, he'd have had to settle for plain lead today*, and from what I've heard he probably would still have passed the background check.

Spree shooter uses a rifle? Ban handguns! Uses a hand gun? Ban scary rifles!

*And butterflies being what they are, hard to say whether that would result in more or less damage.

I don't know of any plan that covers you 100% after you hit the deductible.

His did. It's one of the 'features' of High Deductible Insurance Plans. It might of been watered down since then, but back in the day that was the deal - $5k deductible, certain preventative procedures were paid before that deductible was hit, but after that it was covered 100%.

What other 'gates' are you talking about?

26 officers over ten years is a TINY casualty rate, not worth bothering about.

The dirty secret is that 'Police Officer' doesn't even make the listings for dangerous jobs; it's not the safest job out there, but it's a lot safer than many. Air Crews, fire fighters, loggers, cabbies, etc... Are all more dangerous.

And that's the thing. Police officers are VASTLY more likely to be shot immediately* with their own weapon in a conflict, and it's STILL insignificant. The real reason behind wanting 'smart guns' is the same as the racist 'Saturday night special' bans on cheap guns back in the day. Make firearms more expensive, less useful, discourage people from buying them.

*As I consider it likely that if a 'protected' gun is stolen, the criminals can unlock/bypass/reprogram the firearm given sufficient time.

1. Even old car brakes are more complicated mechanically than trigger assemblies.
2. Said devices you mention are not only far more complicated, but are far larger - enough to contain multiple redundant systems.
3. Said devices don't have to sustain sharp sudden shocks like you get in firearms.
4. Modern trigger assemblies actually tends towards more simple than the old ones, one of the benefits of being able to make complicated shapes easily. We use a 'complicated' part to reduce mechanical complexity(IE fewer moving parts).

It's not always possible. See the 1911 with the flush trigger. Still, on my 686 a proper rod behind the trigger could even prevent it from being cocked. But I'd be extremely careful when mounting the trigger lock on - place it too far forward initially and you could end up tripping the trigger.

Oh, and I checked with my S&W 686 - with the hammer cocked it does indeed lock the cylinder in place.

Oh yeah, and your turning down jobs because of healthcare premium increase being more than the increase in salary is an example of being locked into your current job, which is a bad thing.

Of course, in a market where you obtain your own healthcare you'd probably find that said businesses pay less anyways...
