I'm seeing an increase in frequency of them all over inner London. There must be 8 or 9 that regularly park within a 2 block radius, including a few model threes over the last month or so.Anecdotal evidence:
I live in remoteish rural UK. I'm the only Tesla owner in the village, NEVER seen one at the nearby coffee shop. Pulled in the car park today as a white model S was pulling out, to discover a white model 3 parked there!
BUY TESLA STOCK!
This morning while walking my dog at Battersea Park there were three in the parking lot. A new record.
