A few things about Zurich/Switzerland:
1. In Switzerland vehicles have a license plate on the front, but the ones shown in the episode are on the back of the cars. The front only has the number and the two letters for the "state" without the flags.
2. The interior of the bank looks not like a typical Swiss bank, more like an American bank.
3. The streets shown during the car chase do not look like Swiss streets. In Switzerland the line is white, not yellow/black. The traffic signs shown are not "Swiss" ones. Except for the skyline it is obvious nothing was shot in Switzerland.
