The footpath cycling rules are essentially an attempt to prevent the race to the bottom - consider your options here. Cyclists can use the footpath, but cannot hope to avoid a car attempting to reverse out of their driveway. Or even driving forwards. Pedestrians have less of an issue here because they simply can't go that fast. I rode into the side of a car in this particular situation about 15 years ago - the law is an ass because the citizenry is a bigger ass, in this instance.
It is easier to require the cyclist onto the road for their commute, than attempt to completely change the infrastructure of every driveway in the nation. I think it would possibly be a better offence if it carried no penalty - but created a clear "chain of responsibility" in a court setting. In civil cases, the criminal law is not even necessary to decide fault.
Either way, this is fantastic news, I'll be sure to let everyone know. It's something that gives me pause on the busier roads when I've had the baby seat.
