What p1sses me off is that when there is no data on the car (and there isn’t on ours; nothing on the V5, nothing on DVLA; nothing on Driver Standards Agency which is what TFL references) TFL seem to default to no compliance.
Most people will trust that TFL must be right when in fact they have done fook all investigation.
If TFL don’t have the data, they should right to each keeper explaining this and that the have defaulted to non compliance until you can prove otherwise. At least that will alert the keeper to do some of their own investigations.
I only chased this as I serendipitously noticed that something was not right when I looked through the cars documentation. No idea why I did this, but if I hadn’t that would be a old car needlessly sold on.
