Fortunately my 1 year old has button for everything I need to operate the car, in addition to the touch screen.
What I do like are the blind-spot detectors, and the warning if I deviate from the lane I'm in (without blinking). Also the indicator on the side-mirrors (correct English?) that warn if a car approaches from behind in the blind zone, in case I do want to switch lanes. A camera for reverse driving is also handy.
The car reads traffic signs, and from that display the speed limit. The indicator starts blinking (faintly) if I'm driving above said limit. I would have preferred if it was possible to also turn on a warning sound. There is BTW a slight problem when I start driving, and there are no traffic signs nearby. Sometimes, like when leaving a parking field, it suggests 80 kph. But in general it's very reliable.
As I've said, I don't use the cruise control. To be honest. that's because around where I live there are mostly 50 kph and below zones, with speed limits varying frequently (lower near schools, kindergartens and so on)
Another thing I don't use is the mobile app. I don't see the need for it, and I don't see the need for sharing personal information with Opel. They claim that the GPS works better (more updated maps) if I connect the phone, but it's good enough as it is (and I very rarely drive outside my comfort zone anyway). I have used the app a couple of times, but only to turn on heating 10 minutes before driving, handy during winter. But not essential - the heating equipment is very efficient and fast - I assume that's typical for electric cars.
pibbuR who most of the time moves at 6kph, except when on his in door exercise bike (25-30 on-the-spot kph).
PS. Talking about reliability. My previous car suddenly refused top reverse. Just out of the 5 year guarantee period, and fearing an expensive repair, we decided to replace it (had thought about that for a while). Turns out they fixed that problem through a software upgrade. So we really didn't need to buy a new one, but then we had already almost decided to do that anyway, so it's no big deal. The new one has so far been very reliable, we're quite happy with it. DS
PPS. Young men often like to fix and improve things on their own. I don't think that's possible anymore, due to all the electronics and the software. BTW, I also liked to do things like that, but with very little success. After installing extra lights, driving 300 km on roads without street lighting at night in the north, only able to use near light (probably not correct English), because the fuse burned out whenever switching to ... eh .. far light was not much fun. DS.
PPPS. We were going to Tromsø, to catch a plane to Bergen the next day, planning to stay the night at my in-laws. We arrived there severely delayed at around 2-3 o'clock in the morning. And then the 10 months old youngest one, suggested that maybe it was time to get up now. Ouch! Fortunately, a gentle push down into her bed and comforting commands was good enough. Puh! DS
