good on ya, I have done a similar thing when a woman in a range rover nearly cleaned me out (had to drive onto pavement to avoid her), followed her to her house and gave her a roasting (she was only on phone for a min but still).
When I see someone on an A road on the phone, I actually aim for them, I drive into their lane, and either force them over, so they have to drop phone and steer, or once there was a guy with a baby in the passenger seat (in a chair thing) on a 20mph street, saw him from a distance, he was steering with his knees or something as one hand on phone the other behind his head, I pulled accross the street, stopped got out of the car and confronted the prick.
Although i do chase people down for other reasons too, there was a woman I saw at the weekend in a mk1 punto, and it was crabbing all over the shop, she nearly lost it and span it many times in a few miles, the whole back end was squ if, and the rear wheels were actually really narrow, like they had been smashed in by two trucks at the same time.
I followed and flashed her for a good 2miles, then she pulled off so I followed again, got along side her and forced her over, she was absolutly terrified of what i was going to do, and reached for her phone (I must have some kind of creapy look
) so I walked backwards and pointed to the back end, she then goes, oh that, its been like that for a few months, bought it like that, seems OK enough althogh it does brake funny.
So I had a good chat with her about what to do, so if a woman comes on here with a red badly bodged mk1 then I sent her! I also advised her not to drive it any further as it was a deathtrap (coming from me thats a lot, as I get free cars and use them!).
