Well soccer mums shouldnt be speeding in the first place with kids in the car.
Tradies shouldnt be speeding, especially if they have buisness advertised on their car.
IMO, its a good idea which should deter repeat offenders, well hopefully anyway.
lol, talking to some friends who were over in bali, theres so many scooters over there its so hard to cross the street, their guide just told em to walk out and dont change your pace or stop and they'll all go around you and you'll be fine.
