Swearing. A lot.
Having been caught up in the "Streetly and Great Barr" I really am not fit to be behind the wheel, but how much harm can it do on a Sunday morning? " event".
In no particular order,
The black Audi a5, who was p! sed, lost, or both, alternating between 15mph and stationary, on a 50mph A road,
The black Mercedes C-something who, despite there being nothing at all coming the other way, thought it safest to wait until the lights turned red, before making their right turn, and then proceeding - barely - at warp factor 20(mph), strangely mimicking the p!zzed / lost A5 driver of moments before,
The orange Hyundai, who thought it was safest to drive in the middle of the road at 20mph, only returning to the left side of the road when a car was approaching. Oh, and braking almost to a standstill at each bend, junction, pothole, shadow.......
Any number of Discos, Audis, and Beemer, who thought the inside lane was only for trucks and plebs,
The lady in the Audi Q-barge, who took "speed kills" almost to its logical conclusion, and joined the M5 at 30mph, causing those already on the motorway to have to brake, and those behind her on the slip road to have nowhere to go at all.......
