Another 8 going off road

[sarg]

crazy stupid driver clearly not paying attention, texting perhaps?

However, it also looks like your friend was parked next to a road junction - within 10m is a breach of the Highway Code, the other driver might even be able to get off on the technicality that strictly speaking the 8 was parked illegally
