We have this, well almost all known purchased vehicle for our son. Because Dad says: "I had so one and so we need for our child a Bobby-Car!" The Bobby-Car is the whisper really quietly and makes a pleasant sound, which I find very good. Our son (16 months) for the self-driving still too small, but he sits totally like on the car and tüdelt it around. Sooner or later we will drive going safely. The assembly is a breeze for every dad and every mum and I think it will certainly keep still for more children, because it is super stable. For spatial thinking I find such cars or karts very useful and a good toy, where they can learn a lot by directing and own body movements.
