I was simply prompting the OP to make sure he was watertight before going to the filth with his footage. As it turn out, it's all academic, because the bike seems to be a sensible one.
Fair enough - but let's face it, unplug or remove a battery on even a 2500W eBike and it's instantly and indisputably a push bike, not being capable of assisting the rider in any way. Just saying !
Plus "S-Pedelec" type bikes are in no way not sensible on the roads (which is the only place they are allowed to be riden anyway). Derestricted bikes are allowed on the roads provided they are registered - it's beaurocratic and legislative issues they are subject to and nothing to do with whether they are "sensible" or not.
Your post got misread because it could be interpreted to imply that if OP was cycling assisted at 18-20mph (which he wasn't), he'd as much as lose his basic rights not to be bullied on the roads on account of him "crossing lines" himself. In the context of the driver's actions, regardless of the provisions of the RTA as regards eBikes, that's pretty disingeunous - and I think some of the responses you got were pretty much alluding to same on account of how the post came across. Being cut up like that makes no difference whether you're travelling at 18mph+ under your own leg power or with a nudge from a pair of 'virtual legs'.
The one category of drivers who I've noticed are typically very aware of cyclists and drive sensibly are bus drivers. There's a (probably about 200m) uphill run from box junction traffic lights which merges into a narrowing road without cycle lane shortly before I have to turn right to get home. It's too far to pull out into a dominant position early and I always have to pedal like crazy to get the chance to signal and pull out safely across oncoming cars to turn without unduly interrupting the traffic flow. Most of the cars speed up as the road narrows trying to get past me first and if I dawdle pulling out it leads to all sorts of aggro.
Pulled off pretty aggressively on Kalkhoff yesterday and got up most of the hill at about 18mph with a bus trailing but lagged back to maybe 14-15mph further up the hill before signalling. Bus driver made no attempt to overtake even at that speed over that long a stretch of road. Clearly aware of the conditions ahead and allowing for my possible moves. It was such a noticeable change from the usual behaviour of car drivers it really registered how much less of a stress it is when people are considerate.
Everyone nowadays is in so much of a hurry and wanting to be "first". Sometimes a bit of a talking to is the only way to get them to think about what they're doing.
