Old guys always begin with; "Back in the day" I was a bicycle road racing type, serious road racing, like riding a hundred plus miles in the Ozark hills 3 times a week for training. I can still ride a bike, not as fast nor as long.
As MTVR pointed out, bicycle riders just don't pay attention, with ear bugs blasting away they can't hear what's coming up from behind and then just cut in front of a driver to save three rotations of the pedals. By the same token, drivers don't pay attention and we have 5 times the traffic we did when I was riding. Just isn't safe to be on major routes in town.
I ride my 1800 Trike in town but still try to stay away from heavy traffic, it is mentally draining to ride safely. I'd have to disagree that an e-bike is more dangerous than a motorcycle, it's not the machine that is so dangerous but the nut behind the handlebars.
I've been looking at e-bikes, I don't hike anymore so riding some trails would be more fun than sitting at camp. They had a few at the Moore Overland expo last weekend and the cheapest was $5K!
I was told the top speed on most e-bikes is 32 mph, that isn't fast enough to be in traffic running at 40 or more mph, but some try and it ticks off drivers causing them to take risks to get around them.
I might justify getting an e-bike after I get the boat in the water, it can be a real hike going from a dock to the local bar, not sure about the return trip to the dock.
