First off…I've so very sorry to hear of your accident OP…I hope for a speedy and full recovery for you.
Second…those F'ing extended mirrors…AAARGGG...
I got nailed the exact same way two years ago…******* just wouldn't get over as it was just he and I out on a country road. He smacked me and just kept driving. I'm not sure how I didn't biff but I managed to maintain control. Shoulder was bruised for weeks...
