I have been riding a while and found the Interestate (the Superslab) much safer than secondary roads by and large. Around DC there is LOTS of traffic and idiot cagers. Around town when traffic backs up I tend to be extra cautious and slow down...especially around intersections. Darting in and out of traffic infuriates some drivers and will cause them to challenge you or tailgate you to prove "they are right" and "you are wrong". So, in traffic I try not to do anything to provoke people. I'll usually get into the right lane, slow down, and keep some good space between me and the guy in front. I try to avoid any type of aggressive maneuvers, because the cops will see it as speeding or reckless driving and some cagers will see it as "ohh there's another idiot on a donorcycle" and treat you with contempt. That contempt on their part can often manifest itself in the form of aggressive manuevers around you. Some motorists will attempt to chase you. I've had this happen...trust me they will.
Around DC there are a lot of aggressive drivers in quick cars. So when they see a motorcycle they spaz-out and try to pace you, follow you, or act like morons. Unfortunately they are just fast enough that many of them can keep up with you unless you are prepared to click off 150+ to get away from them. Even then traffic will hold you back and allow them to climb right back on you.
I'd say just ride at off-times, get used to it again, be safe, enjoy your bike, and let the scars heal. You'll be okay. Be safe.
