Round here it finished a long time ago.
Lockdown cyclists disappeared as soon as the weather turned the least bit inclement - early September. Motorists are back to their aggressive behaviour, and jog joggers are still running down the middle of the road rather than using the footpaths wearing headphones blocking out all road noise, and expecting everyone to move out of the way for them.
Nope, the cycling boom is gone, and will not come back other than to a very small extent. Once everyone can go shopping, to the pub, on holiday, to visitor attractions the car will resume its traditional place as the preferred means of transport for the masses - and get off the road you cyclists; you never pay road tax! Borislies' health and exercise regime will disappear into Room 101 along with his personal trainer, who has been there some time.
