Generally speaking, I think the number of them driving cars is becoming more Ltd., but the ones who still are are getting worse.
Like the woman in the passenger seat of the car behind me on the way up Arthur's Seat this evening shouting 'faster', 'faster' at me out of her open window. Then, when they eventually passed, finishing off with 'Tasty! Hahaha!'
I've never been offended by being called tasty or told to go faster, but it did kind of throw me half way through my first (informal) attempt at the The Challenge.
Not that I did too badly in the end - 5 minutes and 12 seconds, which would have put me in 93rd place out of a field of 113, and 19 places ahead of the unicyclist.
