vehicularated 

Adapted to travel in vehicles, specifically pertaining to pets, akin to Domesticated but car-broken instead of house-broken.

My cat Mina has always loved traveling by car --sprawled out on the dashboard-- because she started her vehicularization training early, while just a kitten. She is now vehicularated for gas, diesel and electric vehicles!
