Commuting almost daily for 2 years.

Only one wreck, but it was partially due to road surface. No Injuries, just laid bike down against the curb when a right turner cut me a tad close.

Yes you have to watch for the cars. Hear them first, check them in the mirror.
Note their actions. Be ready to act if they get out of line. I've been right hooked a couple of times, but knew it was coming and slowed to avoid it without incident.

Nothing thrown except for random statements from idiot teens behind the wheel. They think cyclists are *****exual for some reason.

It seemes like the few close calls were all in the first few weeks of riding. Either I have gotten used to them[i dont think so] or I have adjusted my riding style to blend better with the cars.

Be visible, wave at people waitig to turn right or left across you path. Make eye contact and confirm that they actually see you. Look to see if they are on a cell phone. Be extra careful if they are. They don't see anything while on the phone.

In the end, is it dangerous ? Maybe, but not any more so than driving the car. They crash the cars so much it's never mentioned anymore. But when a cyclist or ped gets tagged, it's big news.

Just be aware and you should be fine.
