Remember back in the 60’s, 70’s and early 80’s when cars had vent windows? For those that don’t remember such a thing, vent windows are triangular windows in the front of the driver and passenger windows. They could be unlocked and then angled outward, so they would catch the wind and blow it directly onto your face. People really liked their vent windows, but manufacturers phased them out of newer vehicles since those days. Here’s why:
Almost every car now comes with air conditioning. So if it’s so hot that simply lowering a window won’t cut it, you always have the option of rolling up the windows and turning the temperature down
And the second reason why you don’t see vent windows anymore? Cars are actually more fuel efficient with all of their windows closed and the air conditioner on – even when you factor in the energy used to power the air conditioner.
