The fine particles in our air are increasing.That could be the end for older diesel cars and it could mean expensive retrofitting of dieselfilters for the others.It happened already in France,the Netherlands,Germany,Italy to name a few.
When you take your old banger to these countrys you could be stopped and the keys taken from you.But you will get them back as soon as the local air is in a better state,as soon as the fine particle concentration has fallen.In citys like Paris or Munich or Rotterdam you could get stucked for several month ....Unless you find a towaway vehicle , but these will be scarce since they will be in high demand and they might run on Diesel as well.
