Do not run your RC vehicle in a crowded area such as near a playground or on a busy sidewalk. These things can get up to high speeds. If they hit someone or cause someone to fall while trying to dodge your speeding RC it could land you in court.
On-road RC vehicles are not designed for sharing the road with full-size cars and trucks. Don’t run your RC vehicle on a busy street. It could distract drivers and cause an accident or your expensive RC could get run over and ruined beyond repair.
