What size cones do they usually use near you guys who autocross? The ones around here seem to use those mini plastic ones, and not the normal rubber full size cones. I have seen too many of the plastic ones shatter from getting hit. The rubber ones get dirty but at least they bounce around and dont really damage your car if you hit them

 

^Those (rubber)

 

Seen some around here that use the plastic cones too. They break apart too easily. But I've also seen some people hit the rubber ones, and they get stuck between the tires and fenders. lol

 

Standard size rubber ones with gigantor 3 foot tall ones for some critical elements. I slid sideways through a gigantor cone at 70mph and dented my fender.
