I feel for you…
I’m a motorbike commuter (no other real option due to Brussels location) and have to filter through 30-40km of queues each way.
Been hit twice in 10yrs but miraculously stayed upright both times, though seen more than enough incidents :(
Try & increase viz (stronger lamps/those blue tinted bulbs help as they differentiate you from most cars).
Fluo helmet like the cops over here is good too but less cool ;) (I compromised with Haga replica)
Stick a noisier exhaust on it ( I know some people will hate this suggestion but I really notice the difference in reactions)…
Keep the speed down, and the ‘warning’ you just had will keep you even more alert for the next 3 months…
