I have a '18 Legacy and my wife has a '18 Outback. Both have Eyesight. I use LKA all the time in my car and have never had anything remotely scary happen. My wife keeps LKA off all the time. She can't stand it. The fact that she's constantly drifting right when she drives I'm sure has nothing do with it.

Thanks for the reply. In your first sentence above you say "By law in most countries, they cannot over state your speed. Unless I am misreading what you are saying, my understanding is that in law most countries state that speedos can overstate actual speeds but not UNDERSTATE.

 

I'm not the guy that posted that and I know nothing about the laws here or anywhere else. But...

 

We as drivers look at this as if my speedo says I'm doing 50 and I'm really doing 60 (understated), that's bad. I could get a ticket.

 

However, when looking at laws, they think differently. If you're speedo says' you're doing 60 and you're really doing 50 (overstating), that means that your odometer is also overstating. And that means that instead of your warranty being 36,000 miles your warranty is now only 30,000 real miles. Or, if it's a 36,000 mile lease, you get cheated out of 6,000 miles. To a lawmaker, that's bad.

I'd be grateful if someone smarter than me on the forum could explain why speedo disparity only start at a certain speed, and why do the differences increase incrementally as the vehicle speed increases.

 

I don't really have an explanation, but I'm curious. Can you try setting your system to MPH instead of KPH and see if the discrepancy is still there.
