Guys...chill out!
We live in one of the biggest and busiest cities in the world. London is not 10x worse than other places of similar density. If anything, compared with most American cities it is significantly better. I can tell you that it is also better to drive around in than Toronto as well. Bangkok is a flipping nightmare. Paris is not great. Rome is ridiculous and dangerous.
Just take a step back to remember where you are, how many people travel in and out of London each day, and how many people live and work in London. It is a congested place.
But as a result of that you get bars, restaurants and shops all over the place all buzzing and all great. We have countless different areas to go out in Soho, L.Square, Oxford St, Clapham, Islington, Sloane Sq, Hampstead, Shoreditch, .... I could go on. It is rare in a city to have so many "centers" of shops, bars, restaurants, business and clubs.
We also have a very sophisticated public transport system linking the whole thing together. Despite the fact it occasionally runs late, or not at all, it is a lot better and a lot more sophisticated than many other places in the world. In few cities would you get stations as close as Covent Garden and Leicester Sq for example.
So cheer up!
