I worked on cars for 32 years and never referred to curb side or street side it is right or left. If you are in a car, truck, motorhome or trailer for that matter looking forward right is the curb side and left is the street side, so why not just use right and left as long as you don't get your right hand mixed up with the left you will be ok.
