You just have to take your time and ease back into it. You're the only one who knows for sure and its difficult, but please don't let this incident spoil a great hobby.
You have to ride defensive all the time, try and be aware of everything around you, try to peek in cars and see what the driver is doing.
If possible while watching the car in front see whats happening two/three cars ahead, with experience you learn to read the road.
When stopped at lights never pull close to the car in front, always have an exit route and watch your mirrors for the car behind you.
If ever you feel there is a distracted drive beep your horn, sort blast. If I see a motorist texting and think there not in control I give a short blast, if I get the middle finger I just shrug it off.
You can always wave to someone on the side walk or in another car, you got their attention and they think you beeping at someone else.
I noticed you in New York, are you're coming up to SITA at Lake Placid then ride we a group in the middle get your confidence back.
If you're a new rider and would like, I'm happy to spend some time with you at SITA. I have 35 years ridding experience.
remember, if you unsure beep you horn. :thumbup:
