Child's play.

Tesla and Radio Flyer have launched a Model S for kids. With a top speed of 10 kph, it is only a little slower than the electric cart from Arrow Smart. While the latter has a top speed of 20 kph, mum and dad can limit speed and range via a smartphone. Sensors protect the little ones from collisions. Add a summon function and the toy might just be worth the 599 dollars.
