I'm sure that wearing warmer clothing, keeping windows doors closed will keep in the heat, or open the windows and let a breeze cool you in the hot weather...for 10-20mins but ofc depends...
Here in Romania unfortunately no such a law, so I ask politely, if refused ask why, if again leave their door open or take their car picture... I feel like a jerk sometimes so have been doing it less... also so many car drivers seem to think they have a right rather than are a blight....¯\_(ツ)_/¯
One thing the bus drivers here said is their electronic system resets if they stop their motor, don't know if it's BS , they seem nice guys just not very educated in ecological stuff , like most Romanians..
Nice to see such an article
