The traffic sign reader does not work for 100% of the street signs. And mine does not work at all for the ones painted on the road so check if yours does.
I'm not sure that is true. A policeman once told me that it is not legal to affix a satnav to the windscreen, at least where I had it in the middle, and said it should rather be fitted to the dashboard.
OP it sounds like you are mostly afraid of speeding. So take it easy or take the train.
This sounds very harsh- but I am afraid, this is it. Trains and buses in Switzerland will take you absolutely everywhere, even the remotest valleys and there are excellent deals for tourists available. Having mental issues is not a problem at all, but 'not being fully alert' is, for your sake and everyone else's on and off the road.
Exactly, why a day doesn't go by without an accident in and around ZH and other metropolitan areas. Driving a car is not to be taken for granted. It's bad enough that Swiss roads are over their planned capacities. Any so called short coming is simply too dangerous. A second of distraction is all it takes to have a fatality.
Statistically there are enough people on the road here who aren't driving with due care and attention that n+1 will make no measurable difference to the accident rate.
Good work OP. It takes some doing to get the range of posters who have replied and thanked posts in this thread to agree on something! We just need Treverus, Chuff and ZuriRollt to chime in against you and you'll have the full house.
If you do decide to drive, could you let us know when it will be and where please.
The system of my car that recognizes signs with speed limits has two issues:
1) It doesn't recognize signs painted on the asphalt. Only vertical signs.
2) Sometimes it recognizes signs to the right which aimed at the exit lane from the highway, or smaller roads parallel to the highway. If you slow down to 60 or 50 kmh while on the highway (120 kmh) it's quite risky.
So, speed sign recognition helps, but not possible to rely on it.
Also, how familiar are you with driving through construction zones? I'd say it takes full concentration to drive in reduced lanes while being side to side of a big truck or a bus. I also saw this week a construction zones where the temporary orange lines detached from asphalt due to rain and all us drivers jerked a bit to left and right but happily no contact Anyway, scary moment.
