If you live in an area where it's very hot, it's nice to be able to start the car so that it starts to cool down a little bit before you get in. Especially if you have children.
sorry still do not see the point even in hot areas.
a/c does not work instantly as it takes a few minutes for it get up to full operational cold, also there is tremendous heat build up in the car while its sitting, so you are trying to cool all this excessive heat that's in the vehicle - which takes even longer.
It's more effective to just open all the windows (and sunroof if you have it & hatch too - when parked) on the vehicle for a few minutes to get rid of as much heat as possible, and then turn on the a/c set on recirculate and max and then close everything.
Also a windshield sunshade helps to some degree in keeping the vehicle cooler.
- no expense of buyer a remote start and sometimes the problems associated with it
- save on gas, no wasted fuel idling
- good for the environment
