Road cycling comes with inherent dangers. Any time you ride your bike around cars, you take on some risk. It doesn't matter if you have a $5,000 carbon-frame bike that just eats up the miles or a $100 bike from a garage sale. If you get into an accident with a car, you could get seriously injured.
Often, younger drivers enjoy having small vehicles. As they get older and have families, they may start turning to minivans and trucks and SUVs with third-row seating. But, when they're young, they often buy compact cars or at least smaller vehicles.
