Sorry Rob. Just read a few of your posts (here and other threads). You seem like a really good guy.
Just that "rego" line has been said to me many times over the years and is usually the typical response from gear-head-yobbo's (I am definitely not insinuating that you are one - this is just the usual demographic who says that line to me) who have no clue and never considered getting around any other way than driving.
In turn, the hairs stand up on the back of my neck whenever I see that line come out again, especially on a website dedicated to cycling...
Again, sorry for the semi-aggressive response.
Rob (as well)
