Don't put words into my mouth.
I do not claim that driving is a right, but I do think it is reasonable to say that driving is significantly more important to a country's economic activity, signalled by the amount of investment in road infrastructure in, I would venture, every developed country.
I don't think it is a leap to say that roads are built mainly for motor vehicles and rarely solely for bikes and by extension a bike has less right to a road than a car does.
