1) The AC gets warm; 2) It 'clunks' when it restarts; and 3) 95% of the stops are less than 20-30 seconds. As far as saving gas, I doubt, seriously, it'll save a gallon/year.Why would you choose to waste gas and create more emissions when you aren't moving and can't tell the difference?
Auto stop/start is one of the best ways to save gas we have.
Sorry but you're wrong. Stop/Start makes a significant difference in running costs. Always more than 10% I believe. If it's 10 seconds it saves gas. Theres a good reason everyone is doing it.1) The AC gets warm; 2) It 'clunks' when it restarts; and 3) 95% of the stops are less than 20-30 seconds.

Mine rarely comes on. It was 96 today and the car knows if it is hot outside and will not turn the engine off. I usually measures the voltage and if the AC is running full blast, the car stays on. I have a black car and it is kept out in the sun. So for most of my short trips, it never engages. On long trips, I don't stop so it won't come on anyway. Pretty much the same for cold climates as it won't engage until the engine warms up and then if the blower is going full blast, it won't turn off either. The sweet spot for these devices are moderate temperatures where you don't use much ac or heat.Sorry but you're wrong. Stop/Start makes a significant difference in running costs.

Mine doesn't clunk at all. All you have to do is lift off the brake for it to restart. The only clunking I've seen is when someone tries to gas an unrunning motor.
Can't comment on the AC, but if as you say, it's 20-30 seconds, hard to believe that's a real hard ship to anyone.
Sorry but its hard to fathom some of the old fuel wasting things some cling to while the planet is going up in (gas) fumes.

I googled weather or not these things save and read parts of the first 10 articles that came up and the results were mixed. There were some at both ends of the spectrum. Some did a variety of tests under different conditions again with various results. But the general finding was it is temperature related weather or not they save much money.
Also did you know that electric vehicles can lose close to 1/2 of their range in cold weather?
