The cars are on the small side. which I like for a couple of reasons. 1. Hard to hurt someone and 2. it makes the battery last longer. The remote is a little tricky to learn but I am getting better. They are pretty agile and we have run into each other a number of times and it hasn't hurt them at all. And also. by being small they don't take up much room in the house when we are storing them. I would recommend this product to anyone seeking to have some fun!
