I don’t get why people don’t like start stop. After a while you literally forget it’s there. Just becomes part of what the vehicle does. Lots of benefits, very little negatives. Mostly seems like old people who can’t handle change are the ones complaining.
Since you asked, I don't like stop/start for several reasons...
1. I live in a rural area. And there are very few spots that I might have to stop. Many days I only stop at the one stop sign on my drive home. There is very little traffic, so that stop may even be a rolling stop if it's clear to proceed. So the stop/start system doesn't benefit me on my normal commute.
2. During the summer, when I am driving in an area where stop start does actually work, I don't like the AC compressor to be shut off. It's not so much the change in temps, because that is minimal. It's the change in smell and humidity when the compressor isn't running and the HVAC is only blowing residual cool air.
3. I know it's not the same as a cold start, but your engine is restarting over and over. Oil pressure has dropped to zero, so that needs to build back up again after restarting. Whether more wear is actually happening, I don't know. But it makes sense to me that it would cause at least some amount of wear that wouldn't occur if the engine stays running.
4. I'm an old guy who can't handle change
