Yeah, but why do you think it's your road when in a car, especially when the same attitude exists in places without the tax, or with drivers cars that are exempt, or hell, if you've just not bothered paying it? My bet is it's nothing to do with ~£100 of tax, and everything to do with not wanting to admit you were misled by advertisers into thinking spending tens of thousands of your hard-earned cash on something you thought would give you effortless, fast, convenient transport.
