Current charge times make "recharge when the driver stops for breaks" impossible.

Not really, no. Current charge rates mean you can get about 100 miles of range in 20 minutes on a standard DC charger. If you're a tesla owner that's more like 200 miles of range in 20 minutes.

Big rigs typically get in the range of 8-10mpg, so they're roughly 4 times less efficient than cars. That implies that you could get about 50 miles for 20 minutes of charging on a tech similar to tesla's. Big rig drivers are required to take 10 hours of break in every 21. That 10 hours is enough to add 1500 miles of range, 11 hours is enough to drive roughly 770 miles.

It seems like even with Tesla's current DC charging tech there's *more* than enough ability to charge a big rig for all its current driving time.

That depends entirely on whether the item was designed to withstand people attacking it.

A bomb shelter is defective if someone drops a bomb on it (at the designed distance and explosive power) and it collapses.

A skyscraper is defective if it was designed to withstand a plane impact and it does not.

A car is defective if it was designed to withstand people trying to hack it, and it doesn't.

A car's design is defective if it was not designed to withstand people trying to hack it.

So you're saying it had a defect (the ability to exploit it), but it wasn't defective?

In general, companies don't tend to know about significant defects when they actually ship the item. That doesn't mean that they're not defects.

But anyone sane on the planet would rather have them sit a car in a large, private, open space and demonstrate that they can control all of the controls without endangering anyone's life, especially people who didn't sign up to have their life endangered and were just driving down a public road.

Prison is meant to be reserved for separating people from society who are dangerous until they're not dangerous any more.

The correct sentence for copyright infringement (which does not demonstrate that the perpetrator is a danger to others), is to 1) pay back the person who was wronged (though that's a civil matter), and 2) a fine or community service of some sort.

Utility of being able to drive 500 miles and then 'recharge' in five minutes = lots.

I don't really understand the necessity of this. Realistically, you're gonna be driving at most 70mph, more likely averaging 50-60 over a long journey. You can reasonably do 4 hours before you need to stop for lunch, and another 4 in the afternoon before you're going to want to eat dinner. Both of those meals are gonna take you half an hour.

That means that a range of between 200 and 280 miles is sufficient for pretty much any form of driving save for utter insanity driving all through the night, and frankly, forcing you to stop for half an hour every few during that time I regard as a good thing, not a bad.

That said, I do think the tesla's current ~267mile range (assuming 85->90kWh scales linearly) is a tiny bit on the short side. If they managed to get the thing to 300, that would be pretty much sufficient for all forms of driving.

Once you get down sub 4-5 seconds everything is about traction, not about power. The fact that the P85D/P90D are four wheel drive means that they have a metric fuck ton more traction than a Camaro. Add to that that the Camaro you're talking about did 4 seconds on 1970s tyres, and you get quite easily to a car with 4 wheel drive and a lot of torque can do 0-60 in 2.8 seconds.

Admittedly that's into the range of current super/hyper cars (a McLaren P1, and The Ferrari The Ferrari will both do around 2.3 seconds), but that's not surprising when the current way that said super/hyper cars generate enough torque to do that is with electric motors.

says the moron who has never been at a company where an employee sued for tens of thousands of dollars because one employee decided to look at porn and another employee was "offended".

That's trivial to deal with - you explicitly write it in the company hand book that looking at porn is banned. When the other person is offended, you quickly nip it in the bud by disciplining the person looking at porn.

As I said - if you don't trust the employees, don't employ them.

For reference, there are some enormous companies out there that don't filter the internet (I work for one). They survive just fine simply by saying "don't be idiots and look at porn at work".

If at first you don't succeed, you must be a programmer.
