Mine is 5 year ( and one of 2 year ) For the 5 year old, the step down form car to ground is kind a 'high'. She usually is looking for something to grap on getting out of the car and to reach the ground. Sometimes she hold on the table, sometimes she hold on the seat. And one time she held the doorgrip, that will get the door out of his grip. Something like the handgrip on the roof would be fine but than on the car next to the belt of the frontrow. I have no picture found but I hope you understand what I mean. My 5 year old also can open en close the door. Ofcourse she can climb in and out. But it's more like something luxery to have an handgrip to hold on when you get out. See it als a safety to hold on. I always have trouble getting out of a train because there is no grip to hold on. I kinda have to jump from train to ground. I see my child have the same problem. She also have to kinda jump out of the car to reach the ground
