I installed park distance sensors on the rear of my car, dashcam and I am thinking of putting the park sensors on the front as well, so I can park easier. For intermittent rain I just use C-thru ( in the USA RainX) as that means there are only little drops in light rain, and the rain vanishes over 60kph in any case, along with less bug sticking to the window ( yay, last night was termite night, must have been a million or more plastered over the front of the car in the 30km trip back from the in laws, but only a few marks on the windscreen, and a good number stuck on the wiper arms where they went splat, plus of course the dogs were loving the tasty snacks) as they tend to bounce before splat.
A plug in dongle to interrogate the ECU and other body modules is great, tells you things as well as intermittent faults as well, plus things like more info than the dash is capable of displaying. Things like speed control, radio and such are just nice to have, I can work without them or around them. Navigation as well I would rather it is not part of the car, as those are very often both expensive, clunky and obsolete before the vehicle is sold, or are never updated, or the updates are a massive cost for the value of the actual data itself. Power windows I have working hands, plus I can feel if the channels are binding and service it, not just break the whole lot when it seizes from whatever. ABS great if it is there, but remember ABS does Sweet Fanny Adams if you have either no tread on the tyres, or cheap rubber, or have not serviced the brake system and the pads, rotors or drums are no longer up to spec. decent tyres, decent tread and I have not aquaplaned, even hitting a 10cm deep 50m long section of flooded freeway at 120kph, I just washed the underside and the sides of the road dumping 50kph of energy without braking. Guy behind me spun out, must have had airplane tyres.
Joe, you are right on your skill, but as you are likely a driver in the top 1% of drivers, the most common vehicle is for the 99%, and I am in there as well, will just have to admire your skill, and remember never to drive with you in a hurry. I have a simple philosophy about motor vehicles and planes, never get into one that I am more than the empty unfuelled mass. Helicopters fine, cars fine, but no bikes ( I was cured of that at 15 in high school) and no microlights ( RIP Mowritz, AIB still is puzzled about that one), but great fun in helicopters and planes. Yes, did find out a Porsche 911 can actually fly, even if the landing was somewhat sparky.
