[lug] Breaking braking?

[Carl Wagner]

Good links!

I guess they need to install "the big red button" on the dash like they 
have in data centers.  It could kill the ignition and fuel pump.  At 
least for cars with the push button to start them.

Based on the car and driver article, I would say that Toyota should do a 
firmware upgrade where pressing the start button >= 2 times in quick 
succession should kill the engine.

I guess I will keep driving beaters as they don't have all that fancy 
stuff!  (Not to mention that new cars are a horrible investment).

Carl.
