Do you prefer your car without or without electronics?

I would choose my car not to rely on electronic control to make it run - this allows for an ABS control unit and airbags.

I appreciate the benefits and complexities and prefer a car with multiple electronic devices without which it will not run.

I drive whatever is cheapest.

Pah! That was what? 12-15 miles of glide?
Air Transat managed over 65 miles :)

Toyota want steer by wire in their new cars, and they ultimately want to remove the expensive mechanical backup system which is the real reason for it, cutting costs.
So if you get an electrical failure on a bend you'd lose steering. More likely however after the car has aged and wiring gremlins have had time to get to work, the steering will do it's own thing some of the time so you could be merrily going along on the motorway and suddenly swerve into another lane because you turned the radio up.

90% of the time the part that fails in the com2000 is the mechanical contact switch part (usually for the indicators) & not the electronic part.

The Com2K in the Berlingo has failed in such a way that if the sidelights are on for more than 10 seconds, the horn goes off. Lord knows what that is all about. I never use the sidelights anyway. The only time they get used is at MOT time. Fortunately, the MOT man didn't turn them on for longer than 10 seconds either. The horn failed for a previous owner, and I read with interest only last week that the Com2K was diagnosed as faulty. It all works for now, so it can stay like that.

I've never tried to disassemble one. I do sort of feel the unit itself is being asked to do a bit much, certainly the very first batch of them (all long since replaced) were not quite up to the job in hand I think.

Is it just me but I do not like the general "feel" of the Com2K switchgear when you operate it, compared to the nice "action" feedback received from the earlier switchgear. :oops:

The problem is, without electronics, there's no way to meet the stringent emission and safety requirements :lol:
Pure mechanical era has gone, maybe forever :shock:
