If they can impound a car because of no tax/MOT/insurance, then bikes/scooters shouldn't be a problem
Bikes, scooters, and motorcycles can be hidden indoors. It's harder to do that with cars.
All cyclists/scooterists/e-cyclists must always wear some form of reflective clothing, either top or bottom half, that is easily visible and not covered up (by a backpack/just eat food-box etc)
When cars are required to be luminous yellow and fitted with back-reflecting panels, I'll accept that argument.
There's a lot of drivers out there who can't even not hit something luminous yellow and shiny, as these bollards found out. It's the driver's responsibility to use their eyes.
All cyclists/scooterists/e-cyclists must have have sufficient lights (both front and back, provide more than adequate light to the direction of travel, and are clearly visible to others) on their bike/scooter/e-bike
This is already law.
All cyclists/scooterists/e-cyclists must always wear a helmet
Helmets don't work properly at typical road cycling speeds, they don't protect the rest of the cyclist, and they don't make the motorist less likely to hit the cyclist.
