My son loves this car! He is on the spectrum and I wish he would wear the seatbelt, but for anyone who is wondering, it's a harness style seatbelt and is very safe. There is also a foot pedal for acceleration, and different modes for speed and function. It also plays cute little songs and has working LED headlights and a horn button! After a few hours of play, it's easy to plug in and charge overnight. You will hear an audio message that says, "battery is low" from the car when it needs to be charged.
Very cute little car that can roll through a bit of mud or shallow puddles with ease, and it has no problem with variances in terrain.
For size reference, my son is 10 and is about 4'6" tall. The seat is all the way back and he has plenty of room. My 12 year old daughter has also driven it, and she's about the same height as her younger brother.
GREAT toy car for the kids, definitely recommend!
