I'm a student driver and I'm having some trouble on how to park on a curb (not uphill nor downhill just a normal residential area curb). I know how to make my car completely parallel to the curb, but the issue is I can't really tell how far my right tires are from the curb. (Too far away from 18 inches or too close too the curb itself). Also my driving instructor also blinded the right view Mirror and say the "technique" is to look straight forward, but I still can't tell if I'm too far or too close. Any tips?
