Yeah, that's one of the big problems with bikes. People want all the benefits of using them everywhere (pedestrian only pathways, on roads, on bike lanes), but none of the responsibilities (don't drink and drive, right of way, traffic lights, traffic rules in general). People just don't see them as a serious thing, so they use bikes without any rules, getting themselves and others in danger, minimising the risks.
Not to mention, you could easily kill yourself. If you're biking on the roads (especially in the UK where they're extremely narrow), you better recognize you're partaking in a dangerous activity and take it seriously. At least wear a helmet.
Also, cycling drunk is illegal in many jurisdictions and can get you a DUI in the same way as drunk driving a car. If you're on an e-bike, it's almost certainly illegal, since you're driving a motorized vehicle.
Wow. After a family member of mine being injured by a cyclist crashing into them, reading something like this is quite infuriating.
If you drink, don't drive, even if it's a bicycle.
