I’m not a cycling jersey wearing type- I don’t cover enough miles- but if I were I think I’d like one of the I Pay Road Tax ones. (The IPRT website isn’t loading for me at the moment. Hopefully it’ll be back up soon.) The “You don’t pay road tax.” non argument is one of the weaker ones that certain drivers use to cover their sense of entitlement. The jerseys, and the campaign, may not stop them, but it may derail their train of thought long enough to let you put some logical arguments to them.
