I have mentioned this elsewhere in wordier form, but here's a pic (end of post) and description of part of the problem with drivers here. Red ovals surround the problematic areas. Keep in mind that *except* for the narrow no-passing zones, where I ride in the center of the lane cuz there's no room for anyone to the left anyway, I ride at the right edge of the road, as close as "practicable" to it, if there is any other traffic on the road at the time (usually there is).
Why do drivers find it necessary to wait to pass until the other vehicle they are passing (regardless of size, type, etc) is reaching the narrowest point of the road where it is most dangerous for both of them? Often, where it is ILLEGAL to do so as well (with double-yellow lines for no passing, and sometimes signage for such, as well).
This happens so often here that I am actually inured to it, and expect it, and am shocked when it does not happen.
As an example, this place here, at the south end of a 1/4 mile strip of 31st Ave from Orangewood north halfway to Northern, has a lane either side of the no-passing double-yellow line that is barely one car wide when it reaches the intersection at it's south end, and about the same at it's north end. It has no lane markings at all between those two sections, and is only no-passing at those two points. The rest of it is free-for-all based on the general rules of the road, at 25MPH max.
There's no bicycle lane cuz the road is too narrow for one, but it is a part of the bike path along 31st Ave, which has bike lanes both north and south of that strip.
But...if there is a car behind me at any point on this entire 1/4 mile section, they will hang way back, sometimes going slower than I am (usually just under 20MPH), UNTIL I REACH THAT NO-PASSING ZONE. At that point, they immediately gun their engine, and RACE AROUND ME, to screech to a stop halfway (or all the way) into that 4-way-stop intersection. Last night the guy almost went all the way to the other side of the intersection before he could stop, because the rain had made the road slick.
If we're going north instead, they'll also wait until the same no-passing zone is reached, and then gun their engine and roar past me at up to 40-50MPH (in a 25MPH zone, mind you), and sometimes keep that speed up until htey have to screech to a stop at the still-red traffic light a 1/4 mile north of there, usually behind the line of cars already waiting there. Occasionally they needed to turn right as soon as they exit that narrow no-passing zone, and that usually results in them screeching down to a speed they can make a U turn at (barely), then going BACK SOUTH again right in front of me on the wrong side of the road, to make their turn.
This isnt' the only place this happens at, it's jsut the easiest to illustrate, and one at which it happens almost every day that I pass thru the stretch of road, either northbound or southbound (I commute to work thru it, so at least 5 days a week, 10x total each way--it doesnt' happen everytime I go thru, but often enough to maybe count as half of the time).
Many other places have cars, trucks, and trailers that are parked way too far out into the bike lane to pass them while I'm in hte lane, forcing me to go into the regular traffic lane to do so. Cars will be approaching slowly from behind (at the ~5MPH difference between their legal-speed-limit 25MPH and my max just under 20MPH), until I begin to move leftward to go around the obstacle. At that point, they suddenly gun their engines, and race up to pass me, even though there really isn't enough room to do so, and they sometimes scrape tires on the median curb to their left where there is a center median, or simply go into the oncoming traffic lane if there isn't.
I see this happen to other bicycles, too, and even to other cars on the road. Sometimes a car will be slowing down to turn into a side street, pull into a driveway, or parallel park off to the side of the traffic lane...as soon as they begin to slow and are at a point where they must be most leftward into the traffic lane to do what they're doing, whatever the most dangerous point is for this to happen, is when the cars behind them will suddenly gun their engines and race around them.
There is NO REASON for any of these drivers to do that kind of thing, because all they have to do is keep going exactly like they already were, and they will not be blocked or slowed down IN ANY WAY by whatever I or other vehicles are doing, cuz we'll all be well out of their way before they ever reach us.
