Also a huge advantage is the mobility of a scooter over a bike. With a scooter you are more flexible to changes in your day. Did a friend just message you during lunch to meet up for drinks in a different part of town? No probs, just take the scooter on the tube after work. Did the weather just change drastically? No probs, can quickly change to a different way of commute and the scooter doesn't feel like a huge showstopper whereas with a bike it all becomes really really complicated.

Bicycles in big cities are too inflexible. If all you want is to commute like a sheep from home to work and back to home every day then a bicyle is a great inexpensive and green choice, in every other case it's a problem. Unless of course you are in a small village, where a possible change of plans will still result in a short ride. In London this is not possible. If I was to meet friends spontaneously outside my daily commute area then it would be impossible with a bicycle.

I no longer live in London, but these scooters seem a bit big to go on a metro train.

The smallest folding bicycles (e.g. Brompton) are fine, but scooters must either be balanced upright, exposing dirty wheels, or take up a lot of floor space. No thanks!

In the largest cities like London, if my plans changed I'd just leave the bicycle at work, and take public transport to the party, home, and to work the next day (unless my way home passes work, then I can collect the bicycle).

Subways are hard, but many big cities have overland metros and/or buses that can take bikes just fine. Maybe the trip takes 10m more than the subway ride, but then you have the bike at the other end, speeding up the last mile.
