Hello again! To make room for the live and average MPG bar to fit by the speedo, I immediately deactivated the RSA. Having decided recently to just stick the car in power mode, and enjoy the drive more than the economy, I put the RSA back on. It seems to be hit and miss - I wondered if it needs updating, or is just a little glitchy anyway. It shows both absolute genius (matching matrix and temporary speed limits) and unhelpful or risky advice (120 as a speed limit, blank data when a speed limit exists). As 120 and 80 occasionally pop up, I can guess they are European kilometre per hour postings. However, seeing 120 (kmph) advised in a 50 mph zone isn't too useful. Is it working smoothly for everyone else?
Yeah, sorry - Road Sign Assist! It pops up the speed limit both on the dash speedo, and briefly in the HUD (temporarily replacing the eco rev counter bar). It then stays in place on the main dash. Working perfectly, it keeps the correct speed limit sign in place during the duration of each section. Working imperfectly, it either doesn't keep the sign up for the full length of the road, or not at all, or chooses an incorrect UK limit, or a mystery European one. As it doesn't state mph or kph, seeing an 80 or 120 (double our national limit!) pop up aren't much of an "assistance ". I guess this feature may not be a global thing then.
Glitchy for me too, which I expected. Sometimes I can be driving in a 20mph or 30mph zone, and it would display 100 as the limit in that street. I'd say 90% of the time in my journey, it works properly. Given how many speed cameras are located in London & South East, I leave the notification that I've started to speed at 1mph over the road sign. Somehow, I also managed to set up in the system an audible alert each time I come close to a speed camera. Personally, I'd rather be reminded of the speed limits on that bit of road, rather than my instant MPG, so glad that I have the choice.
It's one of those other things which they haven't offered in Australia. They seem to expect that we can read them ourselves - crazy!! Same as they expect us to be able to park - no self-park on any model offered. Fortunately, I learned to read, and I can park - though, funnily enough, I did my first parallel park on Sunday - 4 mths after taking delivery.
I don't use it for 2 reasons: 1) I tend to look at the road when I drive 2) it is a hit & miss as the system is based on image recognition; essentially the camera sends a live picture to a computer that tries to read signs. In mainland Europe and I think U.K. as well, trucks have stickers by law indicating their max allowed speeds on highways and regional roads and it reads those too without much intelligence. The stickers are small and if I am driving at 130 and the truck at 80, a sign cannot approach me at 50km/h, can it? So you might be on the Autobahn on a no speed limit section, and a 80 speed limit pops out of the blue... It needs a thorough software update. As it is, quite a gimmick I am afraid...
I do not use it as it works only based on speed limit traffic signs and misses the rest completely. For example city speed limit and highway speed limit is not being enforced by traffic signs here in Slovenia but by law. You just get traffic signs for start of city limits and end of city limits which system does not recognize. I hope this stuff works better in Prii with sat nav system. Deactivated the RSA and enjoying the economy stuff instead (current fuel consumption).
I use it, mainly to remind me if I'm drifting slightly over the limit, but also have the Nav one on as well to check. The RSA only puts up what the camera sees, so whatever the last road sign (or sign on a truck) it reads. I've had it miss signs but it's never put up nonsense numbers like 100 or 120 and it only seems to read speed limits, not other signs as indicated in the manual.
Yeah mine also puts up nonsense number occasionally - as someone said it's just trying to detect signs from a camera image, so sometimes it makes mistakes. I find it most useful when in places I don't know well, as you're often very busy trying to decide where you're going and watching traffic, and on occasion you can miss a speed limit sign. The benefit is that it stays on and flashes red for a period after the sign, which can be a helpful reminder to slow down. It does need to be taken just as an aid to make you check, rather than using it as the actual speed limit.
Yeesh. I'd rather prefer the nav-based speed limit signs. At least the data is embedded in the navigation!
I'm not getting the nav version. At almost £800, it just isn't worth it imho, so Mk I eyeball it is for me!
I have road sign assist turned on, but I would prefer if I could receive the notifications on the HUD while keeping the rev counter. It's VERY hit and miss. On my route into work it sometimes spots a sticker on a back of a school bus that asks people not pass faster than 10mph, and tells me I'm in a 10mph zone (I understand why, and this is fine) and at another spot it seems to give me a pictograph indicating that I'm leaving some sort of 110 limit zone (I find this one hard to duplicate but it's generally in the same spot, can't see what causes it) when in fact it's 30 limit. All of this in mind I would still keep it on because it's a prompt for me to check - we have that many variable speed limits I'd rather have an abundance of caution and avoid a fine than risk being caught out.
