E-bikes and e-scooters are out of control, Australia-wide. Half the problem is the unlimited accessibility and ease of purchase of these things, the other half is no age restrictions and no training. And it's not just juveniles, either.
The number of young males in their 20's riding these things at high speed with no registration, onto footpaths, then onto roads, then cutting through traffic, then back onto footpaths, is large.
SWMBO and I were in Albany on the weekend. We filled up at an unattended (card only) servo, on the main road, Albany Hwy. We climbed back into the car and went to drive out the exit onto the highway - and a young bloke about 20 on an e-scooter, doing about 60kmh along the footpath, screamed past the front of the car, missing us by less than a metre.
I was only going slow and looking back up the highway to my right for approaching traffic (there was none), and I didn't even see this bloke on my right, he was going so fast, he had no hi-vis or lighting - and the last thing I expected was a vehicle doing 60kmh on the footpath. Plus, there was signage, posts and other obstructions in front of the servo, that helped conceal the e-scooter rider.
It's time laws were brought in restricting the sale of these things, a requirement for training and licencing (both bike and rider), and rigid enforcement of the rules. We've had idiots here just kill themselves, simply by falling off them at speed.
