i think it is fun to be in a booster seat it is safer,easier to see and funer and if you dont the seatbelt it keeps covering your throught and eye. I am 9 but still have the seatbelt covering my throught and eye so after tax season i will be in a booster it is much safer. plus i can see better out of the car window . iT IS ALSO NOT FOR JUST BABIES! kids with boosters are safer and they look tall out the window kids might want booster seats so they look tall and do not look like a seatbelt is in thier way it also is safe so they do not get hurt from the seat belt. plus a kid that can not see out the window might not see a car coming about to crash. but they might be able to make a new design of car . 3 adultsin front with adult made seat belts and seats. 6 Seats near back with special seats that look more like boosters but built in and does not look look like boosters it just makes higher than the adult seats and a head rest right near the kids head with a special seat belt that does not choke them
