1 the passenger was not driving, the driver was attempting to manoeuvre to let his passenger do the deed, after they went past to much laughter and merryment he did a swerve with the car to intimate it again, so yes the driver was very much involved– jolly japes for them tw*ts, potential serious injury for a cyclist,
2- they should have a stern word and log it for future ref, driving with malicious intent, he may ave only passed test not long- whatever– oh and this is a smallish place ,a very distinct reg, i may see the car again…
JY- have reported it –they seem to have taken it as an offence– have promised to report back….
