I often wonder, the purpose of this is to save resource, and wonder if the starter would fail earlier because of usage, than the one that does not have this technology... what is the cost to manufacturer these starter, do they make pollution during process? what is the final economical/financial/environmental cost to the society? if they have to replace more often, does that make sense to implement this technology? it would mean a waste if gain on CAFE being offset by loss at...EPA?
ie, government rebate on CFL and LED light bulbs, CFL bulbs has mercury and all of them are probably manufacture in China or 3rd world country where environmental protection is lacking... while rebate at my hometown reduce cost of ownership and energy usage, these gain may be meanless compare to wasted generate during the process of making these bulbs.
I recently spend 3~4 hours on replace starter on my Acura TSX by myself, I can probably get it done about 1.5hr if I wanted; that is still a lot of time (money) think about other activities involved getting it replace, searching parts, buying parts, or schedule a time, drive to a shop etc, if so, it's sounds like the cost of gaining CAFE are transfer to the consumer.
here in my city of Toronto most traffic like are not in sync (if they are, then they work to stop traffic); car manufacture, consumer, are being ask and ask, mandate after mandate, urge after urge, to drive and conserve fuel. there is luxury tax, fuel tax, environment tax, carbon tax xxxxxxx.... change to thiner grade oil, ethanol, we consumer had done so much; yet the the group that manage the traffic like act like it has nothing to do with them. can't ask us to do all while themselve does not do any. I have a hard time believe the stop start actually do anything benefit at environment as whole on this planet..
