Some people don't understand how I can look at cars going round in circles and I answer "that's Nascar, not Formula 1!".
Some Formula 1 tracks are normal, bog-standard, roads taken over for the week, such as the famous Monaco, Sepang and Melbourne circuits:
Australian F1 Circuit, a local park turns into a Formula 1 circuit
Monaco F1 Circuit, Where the Streets have no names. But the corners do: Casino, St Devote, Rascasse
Sepang, Malaysia F1 Circuit, built around some amazing high rise buildings, all lit up for a real eye-opening evening race.
The old formula 1 cars don't look amazingly different to today's cars, I think they're the same length and roughly the same height. This little video will show you exactly though:
