Cars + bikes = trouble.
Nothing like a near miss with an auto to get the adrenaline flowing.
The day after we put our dog down, I went out for a ride.
I was totally braindead that day just riding on autopilot -a very bad thing when you share the road with 2000lb, gas-filled projectiles- and nearly rode right out in front of a pickup doing 35-40MPH... just flat out did not see him. Luckily I did and jammed on the brakes toot sweet. Didn't fall, though

But, man, I just sat there for a few minutes and collected myself.
You dodged a bullet. Glad you're OK.
Let's hear for those 50+ year old reflexes!
