The number of motorists who have been fined, after cameras were installed to capture drivers who break the rules, is an indication of how serious a problem this is.
Drivers may not like it, but clear bus lanes help clear the city streets more quickly, allowing public transport and taxis to get out of the congested streets faster.
Tens of thousands have been caught on camera and while some may have been unaware of the enforcement action it is difficult not to realise you are driving in a bus lane ... if you are paying proper attention to road and warning signs.
Therefore, it is fair to assume that many are simply flouting the law and believe they are entitled to drive wherever they like.
A stiff fixed penalty notice dropping through the letter box might change that, but ultimately it would be better if everyone could see the benefits of bus lanes and of public transport for travel in and out of the city centre at peak times.
Like all big cities, Glasgow's roads are congested and something has to be done. Iif bus lanes – and their robust enforcement –help reduce the problem then they will come to be seen by all road users as the good thing they ought to be.
