Not really a save situation as I wasn’t flying, but in the first part of the video, I suppose it could have been deadly even though it looks like he was only running his rear antenna. I can comfortably do at least 40+ mph through here, but I don’t dare. On my way back, he was still there, so the video shows both encounters.

R7 - 24.109

Settings:
Highway
K Wide
K Filter ON
TSF OFF
K Block ON
MRCD OFF

That’s a 25 zone?? That would be 35-50 here. Usually 25 is only posted inside neighborhoods, and even then the main “neighborhood” roads are usually 30. Good save and I agree on the rear antenna.
Yeah there are a bunch of 25 mph zones around here and most of them look like what you see in the video. Absolutely ridiculous. I even think 40 mph is slow, but at least you feel like you’re going somewhere!

Now with school back in session, I keep forgetting how many 40 mph zones become 20 mph for most of the day. Pretty solid encounter on both ends. I respect how open you leave your R7 on K band. Settings like that would probably drive me insane.

Thanks for sharing! Would be a killer spot for running I/O, especially on the bend in the first part of the video.

Yeah we have those flashing school zone signs here when classes are in session, and sometimes LEOs sit right next to them, so you always have to make sure you’re paying attention 100%. I just feel more at ease running the settings I do around here for max sensitivity due to the terrain. I honestly don’t get that many false alerts, and a few here and there don’t bother me anyway. The chatter lets me know the detector is doing its job.

That’s happened in that exact spot before and I was very lucky to have a rabbit that day. The rabbit wasn’t so lucky...

Not in RI. I think that state has got the most abusive posted speed limits and only for one reason.

A-men!

Someone started that other thread about 'where is the only place you drive slow?' For me, it's when I'm in RI :( Extreme caution is required when on any local road.

I do believe it was rear antenna only. The ramp up confirms it when you passed him on the first run, and also the fact that it held it for quite some time after...

When you approached from the other direction, the ramp up was not that lengthy, which proves the fact that the R7's rear horn is indeed way more sensitive than the front one. At least I experience that all the time.

Did some quick time, speed, distance calculations on your video. In the first part of the vid it was 17 seconds from first detection to the bear. doing a calculation of you driving 25 and 30mph and averaging those gives about a ~685ft detection. Second part using the same calculation method resulted in a detection range of about ~2,984ft.

Don't know your exact speed and if it was maintained through out the detection periods but, should be fairly accurate.

Thanks for that. Looks good to me as I usually keep it around 30 through there and slow right to 25 in the 25 mph zone.

Might be an unpopular opinion in these parts, but 25 mph speed limits make a lot more sense in many situations than drivers realize. The death rate for pedestrians hit by a car stays under 10% up to around 30mph (typical 25mph zone speeds) but jumps to closer to 50% once you get into the 36-45mph range (typical 35mph speeds). 25mph zones are also way more friendly to bikers than 35 zones because the speed differential as a percentage is far lower.

Low interstate speed limits are garbage, and 35mph zones on two lane country roads that should be 50s are silly too. But doing a lot of cycling and living on a 35mph road that should really be a 25 has given me a newfound appreciation for the value of low speed limits in heavy pedestrian areas or places where the road will likely be shared with cyclists.

24.109 wow
24.070 is the lowest I’ve seen being used here. Until I was on the return trip, I had 24.209 stuck in my head and I was thinking, “s**t that’s close to K block range.” I was glad that it ended up being 24.109 and that I had read it wrong on the first pass.

Yeah I believe so. I don’t have MRCD here, so I don’t focus on it too much, but I remember the talk about the R1/R3 not being able to detect lower than 24.050, and the R7 was made to detect as low as 23.950, so I would say 24.070 is in the ballpark.

A problem with 20 or 25 MPH speed limits is that it is difficult to rein in a modern car to that speed for long and requires taking your eyes off the road frequently to monitor the speedometer. Most cars cruise controls will not function below 25 and many cars even below 30. Thus, a speed limit of 30 MPH would be easier to abide by setting cruise control and probably safer because you could keep your eyes on the road. Of course, if revenue generation is the true purpose, these matters are reasons for a 20 MPH PSL.
