but the SMIDNSY is not going to hear a loud can until it's too late.
I get loud cans as I like the sound, I don't try and justify it as a safety feature.
I love the sound, was a real noisy anti-social ( though they hadn't invented the term ) twat as a kid, but now an olde farte I worry about all the moaners that I laughed at as a kid.
50 years ago a few moaning old gits was just that. Now it gets in the papers and useless politician types grab it with open arms as vote winners.
Same applies to speed limits, I deliberately slow where it will win brownie points for bikers, like the lady on the horse the other day, her husband could be the local MP but gladly stick up two fingers where I'm pretty sure I can get away with it. Even a Wee can earn you porridge, just, with the right wind behind you.
