Traffic is not the problem - you cannot catch the virus sitting in your car. The problem is where people end up - most are heading for work and hopefully, employers have health and safety measures in place.
We cannot shutdown the entire economy for 12 months - getting vulnerable groups to self isolate is probably the right strategy. I say probably, since nobody knows - the whole of Europe is in a massive experiment, since we have not experienced anything like this in modern times (1918 was different - people just fell ill and many died from Spanish flu). The point is this, in a modern democracy, it is politically impossible to let nature take its course, hence the various lock-downs - those cannot be sustained indefinitely, so only time will tell when measures are relaxed.
