I live in WI where we get temperature extremes: well below zero in the winter and up to 100 in the summer. In the winter, my heater and heated seats are warming me within 2 miles from home (about 3 minutes). Same with cooling in the summer. If I had a remote starter I doubt I would ever use it.
It seem to me like one of the dumbest ideas unless you have some underlying health condition that prevents you from being able to scrape your icy windows in the winter for the following reasons.
1 It wastes fuel
2 It wastes money
3 It is harmful for the environment, spewing extra exhaust unnecessarily.
4 It is harmful to the engine - it is best for the engine to be in motion as quickly as possible after starting the engine to ensure the best lubrication.
5 It wastes time - I watch co-workers start their engines and then wait for their vehicle to warm up for 5-10 minutes before leaving work. I can be half way home in that amount of time.
I can think of a lot better ways to spend my money.
