Perhaps it's me but I have been stung so many times with these controlled zones.

Dartford crossing, London - forgot to pay

Heathrow drop off - forgot to pay

ULEZ Old Street - forgot to pay

Mersey Gateway bridge, Liverpool - forgot to pay

It seems like a deliberate design pattern to make revenue.

I can't exactly login and pay whilst driving.

Or a design pattern to make you consider if you actually need to drive all those instances?

All of the TFL ones can be paid at any point up to three days after driving into the zone. That's plenty of time. Others are probably the same.

I guess it's like turn signals: If you can't do it right, then just don't drive.
