I think all these motoring offences could all be dealt with under the old "driving without due care & attention" law

"Driving without due care and attention carries a penalty of either a disqualification, or between 3 and 9 points. You can also be faced with a fine up to £2,500 depending on the nature of the incident"

and as regards fines,i think they are already means tested as a defendant has to fill out a statement of means form,I,m sure a lot of these new laws are just to show that the government is doing something,a lot of offences could be dealt with under existing laws and at the discretion of the copper.

Sadly, therefore, there are now far fewer police to enforce a law that is designed to protect all road users and pedestrians"
