You can ask anyone in St. Gallen - no-one owns a car, they all cycle or walk.

A place of work that can not be reached on foot, by bike at the very most, is almost in-acceptable for Swiss citizens.
One of the first questions presented to me, when I was interviewed for the job I have at the moment was:
"Are you sure it won't be too much for you to drive 40 kmh to work every day?"
I replied, that I had regularly commuted backwards and forwards between Stuttgart and St. Gallen (250 km) previously - that seemed to stump them.

The question is, though, if no-one in St. Gallen owns a car (or Zurich/Bern/Lucerne etc. for that matter - they all say the same) why is it, that there is never ever a parking space available when you need one?

I used to have a lady-friend in SG. I was never once on time when I visited her, because I always spent an hour driving around looking for a parking slot!
Hardly any of the houses in SG have garages and the roads are packed tight with parked cars. The parking spaces I found, more often than not entailed either a twenty-minute-walk or a steep fine.
I gave up in the end, it was just too nerve wracking, I exchanged her for a lady in the countryside!

Worse still, though, are the multi story car parks in towns and shopping centres. There are enough of those, but the Swiss engineer that worked out how wide a parking space needs to be, probably owned an Austin 7, a Citroen 2CV or some other post-war model. The standard width of a Swiss paring slot is 190 cm. The result:
You can hardly open your door wide enough to squeeze out of, or in to the car. With inconsiderate drivers left and right, it is impossible to leave your vehicle!
[Please read carefully - nowhere on this page, does it state that the Swiss are inconsiderate drivers, the Swiss don't have cars - they say.]

On Saturday I drove into a supermarket Parkhaus. I turned round to get my shopping bag off the rear seat and while I was doing so, someone drove into the slot next to me, jumped out of his car - beep-beep - and walked off leaving me stranded in my car! I sounded my horn irately, but he just ignored the noise and disappeared into the crowds! In the end I had to reverse back out of the slot and find another one!
Bu**er the ba***rd!

It is interesting, by the way, in this tiny country where no-one owns a car, how many American vehicles you see around - and not a single one of them fits into a Swiss parking slot!
