That's a pretty big stretch to me, especially since key fobs can usually unlock a door from across the parking lot without even leaving the building.

I live in a cold climate. Remote start isn't even necessary much less very necessary. I start the car, then clean off all the snow and leave. Running the engine isn't going to remove a foot of snow off the windshield and it definitely won't off the roof or hood.

Regardless remote starters do not need the web or a phone, they existed in the 1990s.
