As a retired auto technician, I have often thought the auto industry should have hired a few less engineers & a few more technicians. This automatic stop-start thing sounded stupid from day one. Sure it might save a little gas, but what other possibilities for problems? You could stay home & save gas, too. There are some other design features that would do well not to have been put in production as well. Maybe some of these were pushed onto engineering by sales?
As a retired mech. eng. I can assure you that crap like automatic shutdown wasn’t originated by an engineer. It’s called government coercion/regulation. Or perhaps Borg Warner and Exide if either is still in business.
