I've been living in LA for a while now and one thing I've noticed is that the area commonly referred to as "LA" is huge and that things can vary considerably from one part of town to another.

The real "startup" hub in the Los Angeles area seems to be in Santa Monica, far from downtown LA, where the crackdown in the article seems to be taking place, and outside the jurisdiction of LAPD. It's home of many startups, near UCLA and home of at least one incubator (Mucker Lab).

I've worked in Santa Monica during my time here and it's surprisingly bike and pedestrian friendly (as are most of the beach cities). I don't currently work at a startup, but the my current employer has indoor bike rakes that are well used as did my previous (startup) employer. Startups chose this part of town over downtown LA, or other parts of town for many reasons, in spite of high rents for office space. They do so for many reasons, but I have a feeling that one is the ability for folks to get to work in a variety of ways, including on foot or by bike.
