In my neighborhood, Lego cars are a sport. Barbecues are held where friends, parents, and family come together to socialize and watch the kids race cars. I myself am 14, and I still play around. 8-stud wide are the norm, and that's what we construct. Here are the fastest, most secure and advanced cars in this neighborhood. Limited photos. Some cars have already retired.Sorry; I never found out about this site until recently.
