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.
