NEVER let Teslas or other EVs out into traffic (unless driving one yourself). You have to burn fuel to wait for them in your IC car and often slow down then speed up. The Tesla left waiting, however, creates no CO2 when not moving and won't have to slow down/speed up. I'm sure environmentally conscious Tesla owners won't mind at all if noone ever lets them into trafic. Its for the good of the planet after all.
