The more you ride on the streets, the more comfortable you get with the traffic.
I remember when I first started out, I would always try to keep up to speed with the traffic, big mistake. Just go at your own pace, & let the traffic around you adjust.
Its easier for them to figure you out when you pace rather than if you're trying to go all out.
I have to cycle/commute on streets without bike lanes so I got use to it real fast.

Cycling made me a better driver, I'm so much more aware of my surroundings. You get detached trapped in a vehicle.
