Ignition vs. Roll start? - Toyota Yaris Forums

dingbat · 05-17-2010, 04:49 PM

Interesting thread. Got me thinking about some things.

What does the extra wear an tear on the car translate to in barrels of crude? If the life of the starter, trany, etc. is shortened, how much energy does it take to manufacture, transport, and install those parts? Is it less than the amount saved by this practice and how much less?

If shutting the engine off when coasting does increase the risk of accident, what is the percentage of people doing this that will end up in an accident? Will the gas savings of all the other folks who don't end up in an accident off-set the equivalent cost in crude of the tow truck, police cruiser, medical emergency vehicle, being run to and from the scene for the one that does? The cost of replacement parts, installation of those parts etc......?
