Most towns and cities will modernize. For example Sheffeild (UK) has few roads in the center now, many electric trams are used, with park & ride bus systems in use. The majour road is the highway (M1) that goes around the city and connects with all the other huge roads. So the result is; less roads in urban areas, most roads around urban areas. Countryside: small alternative fuel refinerys with bandits and biker boys running decoy petrol tankers off the road!
