I read somewhere, that person who invented the smart motorway system has said the problem with them is the government has cut out too much out of the system to save money.
Biker groups want the banned because they are not monitored by computer (with back up systems) but by a human, who can take up to 45 minutes to notice a broken down vehicle, or other issues, and then update the warning signs (or switch them off when the issue has cleared).
Another great waste of tax payers money
