dude, 2 accidents when ur 16 is ALOT. yea theyre just minor ones, but maybe these little ones are trying to tell you something. i would first get rid of the celica for a good 6 months and practice driving on a cheaper car, cause the celica is not the easiest car to drive and you dont have a good view of all around you in the car, get a camry or a corolla, these things are the easiest stuff you can drive. take some driving instructions, they will help. learn how to judge, do things slowly and nicely instead of rushing it and hitting others. plus its parking and ur dads car is right in front of you and its at home, uve been there like 200 times. basically you dont have good judgement, and you need practice, and take it seriously. same shit happening twice you should be serious now and you dont seem like it. learn from it and try to avoid it.
