I was travelling down a busy road this morning and I was lane splitting. I guess I overestimated my clearance because I scraped a car on the right hand side of me with my side mirror. When I say 'scraped' my side mirror grazed his with a bump. I was travelling very slowly trying to weave my way in and out and I don't think I did any damage or if so then only very minor cosmetic damage. The traffic started moving so I had to ride off swearing under my breath. I didn't know what else to do. Now I feel like a guilty school boy. What should I do?
