Why cars heat up so fast
A vehicle acts like a greenhouse. Shortwave radiation from the sun passes through the windows and heats the dashboard, seats, and steering wheel. These surfaces then radiate longwave heat, which cannot easily escape through the glass. This trapped heat causes interior temperatures to spike drastically within just 10 minutes.
Cracking the windows slightly does little to slow down this rapid temperature rise.
