Unfortunately for e-scooters and other novel vehicles, the government agency in the Netherlands that handles vehicle certification (RDW) is notoriously bureaucratic. By default any new type of vehicle is forbidden to use on public roads until they certified it. On several occasions, e-scooter owners had their vehicle impounded and in one case even scrapped. Which is a real shame, as the infrastructure is perfect.
Whenever i come back from the Netherlands to the UK, i get slightly depressed as I cycle to work, on bumpy, dangerous pot holed roads
