That path has been there a long time and is actually quite popular with cyclists as it goes alongside a very busy road that has an almost permanent queue on one side and lots of big lorries/coaches coming along the other side, so it's quite challenging to filter past the stationery vehicles without getting in the way of oncoming traffic.

For some more giggles, here's one of my favourite bits of "infrastructure" that's further along that same road (Coronation Rd, A370) on the other side. 5m of faded paint.

lol that's a place where a modal filter would be perfect; they could make a "hole" in the curb to only let bikes go straight through. Instead, they decided to put 5 metres of white paint in a random way. Great!
