Some flaw

The car itself is very comfortable for our son but we remain somewhat as "pushing" parents on the track. We are quite large (1.73 & 1.80), therefore, can be the car rather uncomfortable slide as the slide is very low. If one uses the reversible handle to the other side, it can be barely pushing unless one pushes beside the car. Initially squeaked very the suspension which has but now retracted and now works silently.
