Was on a bit of a drive today through some country roads and came across a learner driver parked on the side of the road with all the learner plates on the car (Corser), as i overtook it the b2 screemed out that i had been hit by Laser, (*** myself) so thought i would go back and see where they were hiding as you do, but a tad slower, on the way back up the learner was coming toward me and as we passed the b2 went off again, whats that all about.
