Depends on where you are driving and how well timed the lights are. Living in a smaller town, beating the timed lights or the delay after a waiting car signals a change can be very beneficial. The worst case is that you wind up moving forward as soon as everyone else. Best case you get an extra green light.

As usual a purely physics based approach assumes a lot of variables. It takes me little thought to imagine many problems with this, I live in Oklahoma and this situation isn't rare. The described deceleration is assuming the cubic object is traveling on a friction-less surface that hits a static object at a known rate in an inelastic collision. So many more variables. Vehicle flips, vehicle spins and takes out the 2-3 vehicles behind it, vehicle is bumped into a guard rail or bridge support and has a very very rapid rate of change in velocity. Or a truck is jarred and the shotgun in the back seat shoots too many holes in your assumptions.

Yes, control systems can react much faster than humans; however, the statement "The car behind will apply maximum braking force the very moment a single cycle of it's control loop happens (probably 1/1000 or a second or so)." is almost patently absurd and shows a best a limited understanding of tuning a control loop. Yes, a reaction will happen within a single cycle, and yes 1kHz is reasonable, but assuming maximum braking force is assuming it is only a proportional control that is tuned to be highly reactive. I would challenge anyone to ride in a car that has a purely proportional control that would react as described. You'd sue me for whiplash.

"Even though Abrams' last known direct contribution to Lost was the script to the season 3 premiere, "A Tale of Two Cities" (which he co-wrote with Damon Lindelof), and he had stopped being the main driving force behind the direction of the show as early as season 1, instead leaving Lindelof and Carlton Cuse as the showrunners, a considerable part of the (casual) audience still considers Abrams to be the man in charge of the show." http://lostpedia.wikia.com/wiki/J.J._Abrams

The US has a vast supply of gold and land backing its currency, at least theoretically it has something backing it. I realize what a fiat currency is, i am just pointing out that it could pay creditors.

This would do no more than to make people unlock their home defense and self defense weapons daily. If the one day you forgot something happened, then you'd be frantically swiping a sweaty finger across a fingerprint scanner that is already mediocre to begin with. RFID seems the best option in terms of securing personal weapons, but this isn't necessarily the problem when looking at fixing mass shootings. This assumes the owner isn't the mass murder type. The reality is that so much of our comfort and security in life revolves around people acting under the normal confines of society. Someone could kill dozens of people driving to work in the morning by forcing people off the road for example.

Write off's only save you whatever you would have paid in taxes on that money. You've still spent the money. It's not like write off's magically pay for themselves. Given the fact that business lines are significantly more expensive and the fact that you can write off a consumer line there's not really a point.
