Ordered a takeaway a few months back from Uber Eats, it said the delivery driver was on a bicycle which given the distance concerned me that i'd be getting cold food. 15 minutes later I can see him powering his bicycle down the local bypass at a decent rate, probably 60-70 no doubt given how fast the icon was moving.
Just before he got to my house however he seemed to swap his bike for a knackered looking Pug 206 that a quick check suggests was uninsured & had no MOT as of about 18 months prior.
And therein lies the problem.
These drivers buy/register bicycle delivery accounts because the rates are different, in favour of the driver & no need for UE do ask for vehicle documents to prove they're legal.
So in your case you have a person commiting
Fraud
Driving without insurance
Driving without a valid MOT
Wouldn't surprise me if he wasn't licenced either.
Personally I'd be on to local plod and getting the moron off the roads.
