AFAIK in the UK there is no law against being drunk in charge of a push bike.
There is. I don't know the exact wording of it's title, but you can be done for riding a bike on public roads, whilst being under the influence of alcohol and/or drugs. I think the legal limits for driving apply. You can be done for riding a horse whilst drunk, too. As they can't penalise you like they can car drivers, they can fine you a hefty amount.
I have woken up with huge hangovers and no idea how I got home many times in the past and found my bike neatly parked in the hall…… I've also ended up in casualty… never been arrested though.
Same here, re the bike being safely inside. I've woken up in a panic, wondering where TF my bike was, but it's been fine. My flatmate once found my bike outside the flat, not locked up, one night. My most expensive bike, too…
Not ended up in casualty or been arrested while on my bike, apart from the time I got done for screaming abuse to some chunt in a BMW.
Last year I had a crash late one night, whilst pissed. Have no recollection of the crash at all, but suffered concussion, broke my favourite helmet, done my elbow, shoulder and hip in (elbow is still a bit fecked). Missed a mate's wedding because of the concussion. 🙁
Hopefully I have. I don't get pissed if I'm on my bike any more. It's not worth the risk.
