yes it should free roll
yes
If the surface material is smoother and slipperier, the toy car will go faster. However, if the surface material is bumpier, then the toy car will not go as far.
If it's parked on a flat it should not roll at all
Surface material can impact how far a toy car will roll. Smooth surfaces like hardwood floors or concrete allow for less friction and the car can roll farther. Rough surfaces like carpet or grass create more friction, slowing down the car and reducing the distance it can travel.
I believe carbon fiber is the best material
if your going to be of roading then you should look for a roll cage in the car ( i think it usually doesn't come with one) but definitely the material on the outside of the car. Also the handling especially if it is a high car for a bit steep turns.
Aluminum
Woven nylon straps are the best materials for car bras.
It is best to leave it parked and it is possible for it to roll away, depending on the car.
Steer very gently to the side that is on the ground, too quickly and the vehicle will over correct and roll the other way.
If you want to build a car out of recycled and waste material, you should have knowledge on how a car is built. Working with someone who is familiar with rebuilding cars are key to making a successful car out of waste material.
