I've heard motorists make your argument, but on many of the 4-6 roads here (40-45mph limit), drivers in the right lane are routinely slowed to 20-25mph due to traffic entering and leaving all the shopping centers. This does not seem to pose a danger to the 40-55mph traffic in the center lanes (or they would not speed). I disagree that slow bicyclists are any worse than slow motorists and should not have access to these roads or destinations. (Comments from many motorists and some confused LEO.)

Your environment sounds different from mine, but I'm not sympathetic to the motorists' argument that they should slow only for motor vehicles, and bicyclists should not have access to these roads or to shopping centers etc. located on roads where drivers want to go fast.

Personally, I prefer to bicycle 15-25 mph because bicycling 10mph takes 2-3 times as long, but I think slower bicyclists should also be allowed to ride to any destination they want, and have access to any public road they need to get there.

I found it more efficient to ride quickly, and cool off / change at my destination than take twice as long riding, especially in the summer when even walking will generate sweat.
