The average European drives fewer miles, gets fewer tickets, and most their roads have lower speed limits. At least in France, England, Italy, Portugal, and Spain. It's not littered with sports cars doing the Le Mans thing on public roads. LA drivers go faster and I see more 500+ HP track cars in LA. The only place I saw more sports cars than LA was old Paris, but it was during the Paris Air Show. Lots of foreign big spenders present and armed guards. Sheikhs and such. In the US, it is not odd around here to have 80 kph city streets in residential zones. 90 for 2 lane farm road. 120 is normal controlled access for much of the country. We had a lot of race tracks, but urban sprawl moves them further and further away. There are only 3 road courses within short distance to me, California Speedway, Willow Springs, and Buttonwillow. A couple hours more will get you to 2 tracks in the Las Vegas area and one in AZ. The most common form of participant motorsport in the USA is not drag racing, but it does make TV more interesting since idiots call street racing by the name of drag racing. Street racing uses trees, curves, curbs, potholes, pedestrians, animals, bicyclists, spectator cars, parked cars, oncoming traffic, stoplights, police chases, and normally requires alcohol or teenage peer pressure to function correctly. Alcohol for the adults who never grew up so they can act 18 years old. None of that is required for drag racing since it's closed course event with safety equipment and rules, with only 1 way traffic. The most common is a form closed course driving is a roadracing time trial that has speeds capped at about 60 mph called Solo2 or AutoX (same, one is sanctioned by the SCCA, the other is informal, but same sport). It's everywhere. All you need is a helmet and a car.
