This is a very random question, but DD1's driving instructor recommended purchasing orange traffic cones for certain driving exercises (figure eights, controlling speed, turns, parking, etc). Can anyone chime in on how many I would need? I see a set of five orange cones on Amazon and was leaning towards that. There is also a set of 10. They aren't cheap. I have no idea how many would be needed for this sort of thing.
Thanks for any advice!
