Re: What is the point ?
modern "driver assistance" features because they work. Proximity radar and line assist help in dense traffic - especially when stop/start queues form.
No. I have these. They are crap in heavy traffic. They are influenced constantly by the actions of other drivers and when there are a lot of cars close together then they become ridiculous. They are only really good for less dense traffic. Incidentally, the wide load overhanging your lane would cause the car to brake, not continue to try to pass. I would expect not to be lane keeping in a lane that has an obstruction in it anyway, a driver's responsibility.
if you have your windshields coated with rain repellent
I have no problem seeing through my windscreen, the wipers in good condition will keep it clear enough. Fog and spray, though, are a different matter.
100% focus. The reality is that none of us can maintain that for hours,
It's still needed and it's still our duty to try.
The roads are an awful place to drive these days, and certainly no playground. There's no way I'm going driving without a real need. I avoid it a lot. I've also mentioned a few reasons, I haven't touched on the worst one yet, the behaviour of other road users.
