I agree about the bicycle thing. If bicycles and normal people can traverse on the same path through parks and trails and whatnot, why the hell can't they share a freakin' sidewalk? I've ridden my bike on the sidewalk since I got my first at age 8. I only ran in to a fat teenage girl once and that was when I was learning to ride someone else's bike when I was about 6. I got hurt more than she did, and I was alright (bloody lip, that's it).
In my city, it is against city bylaw to ride your bike on a sidewalk because the sidewalk is for "pedestrians only" and that both bikers and car drivers must learn to share the road. If you ask me, that's a load of bullshit. Unless everyone can pedal like an Olympic athlete, bikers are much slower on the road than drivers and can pedal probably from 10-20 km/hr. Ergo, bikers are a real nuisance to drivers and there is nothing drivers can do about it.
That, & streets with no sidewalks, that tends to tick me off. Thankfully there aren't too many of those around here, but, there are enough to frusterate me. Not to mention, I hate the fact that people on bicycles are considered pedestrians. I don't know how many times I've had to swerve to avoid some moron riding his bike in the street, since he can't ride it on the sidewalk. If you ask me(& you won't/didn't), they are pedestrians too. If a buy on a bike, runs into a guy walking, they might hurt for a week. But if a guy on a bike, hits a car! They might be dead for a week! Possibly longer!
That's not the point though. A pedestrian is defined as a person who goes or travels
on foot. When you get on a bike, you're automatically considered a cyclist. Therefore, any privileges you have as a pedestrian go out the window the moment you put both feet on those pedals. There is a reason why we're told to dismount from our bikes and walk them when we cross the street. It's not just for safety.
