I was shocked at how many keypresses it takes to make it slightly warmer in a Tesla.

In my Tesla Model S it takes precisely one to raise the cabin temperature by 0.5°C; press again and again to raise it by whatever amount you want, or I can use a voice command "Increase drivers temperature" to raise it by 1.5°C.
