I get buzzed by one of those at least once a day while riding. It's one thing to use our bike racks but when they start using our bike lanes that really gets annoying. Plus they usually cut by me really close with no warning other than the noise of their engines. I can't tell if they are coming in the bike lane behind me or in the traffic next to me so it's always a surprise pass by these guys. And to top it all off the exhaust from these things are terrible.
