As a former bicycle messenger I'm opposed to it. The trails are filled with baby strollers and inline skaters moving in and out of lanes. typically there is no right of way when crossing roads or entrances to parking lots. Blind corners with overgrown vegetation are par for the course. Riding in traffic is an absolute pleasure when you know how to draft vehicles. The suction created by larger box trucks can actually…
Of course you are opposed, you are not the target audience. Bike infrastructure is there to let your average person bike at 10mph to work/school/the grocery store. It's not supposed to be a racing track. > Riding in traffic is an absolute pleasure when you know how to draft vehicles. The suction created by larger box trucks can actually pull you along with minimal effort. Well, I chuckled ;) Just FYI, if you're "draf…
Box trucks are good for beginners because you do not need to be nearly as close. Slightly ahead of the boundary area of the aerodynamic turbulence feels optimal. In dusty conditions you may be able to visually observe this. Also, they generally cannot stop as quickly. Truck drivers know their routes and will more likely hit all of the lights at a uniform speed. You'll more easily hear their motor and gear shifts.
Yes, there are idiots who will try to brake check you, but they are mostly driving cars. A slight turn allows you to pass on the inside. The entire maneuver happens faster than braking. Braking is actually a mistake here, because you can loose traction and the ability to avoid obstacles.
For the rest of your comment, casual cyclists should prefer lower traffic streets and routes. By working incrementally they can build up their comfort levels. Again, the idea that they shouldn't gain the ability to ride in traffic or should have an expectation to never encounter traffic is a recipe for disaster.
It isn't about racing or being the fastest, but learning to cycle, feeling comfortable, interacting with traffic safely and not making a pest of yourself. That can only happen with the right set of expectations. Separate infrastructure doesn't help novices develop the necessary skills.
