Lets be clear, I am a driver, a cyclist and a pedestrian.
The primary issue I see is as follows:
It slowest moving/most venerable object takes the least care in ensuring its own safety.
Pedestrians tend to assume bikes and cars will stop for them so they don’t look.
Cyclists tend to assume they are ok and cars can avoid them (its the law don’t you know) and pedestrians get in the way constantly because they’re to busy on their phones.
Drivers, well have to watch in all directions and are responsible for everyone errors.
I was taught a simple safety rule, if its bigger it wins even if you’re right, so don’t get in its way. Translation!
Pedestrians watch before you step, you lose in all encounters.
Cyclist respect pedestrians and cars! Don’t assume you are seen, remember 200lbs vs 4000lbs you lose.
Drivers respect all, drive to allow those behind you a chance to react, assume those ahead didn’t see you, make eye contact with all.
Its not speed that causes the issue but assumption the other will take responsibility to avoid the issue. Stop being a me generation, be a we generation so that we all watch and care for each other. The only this speed does is make it happen faster (good or bad).
BTW this applies skiing as well.
