So this is something that's been on my mind for some time. Finally had a day off to play around and test the theory.
Subaru Eyesight has a set of cameras above the windshield that watch the road in front of you. They result in features like lane keep, ADAPTIVE Cruise Control, and automatic emergency braking. The first one is OK, the second one is great, and the third one makes the entire system worth it. One use and it pays for itself. Subaru often cites a study of the system resulting in an 85% decrease in rear end collisions. Based on my previous testing with a frog and experiencing it for nearly 60k miles I absolutely think that number is realistic.
I've experienced Eyesight detecting people running in the road. Of course, I've stopped for those people. But what if it was a deer? What if I just didn't see it?
I included some footage from a friend in the opening of my video of the scenario I'm talking about.
No warning at all just a deer running into the road in an otherwise calm quiet night. The deer did not make it unfortunately.
So yes, I'm talking about a serious topic but thought I'd try to be more jovial about it. So I went and found an inflatable deer and put it on the road and drove into it for science.
I originally planned two tests but we ended up doing three. One with the deer standing in the road. One with the deer running completely across the road. One with the deer standing in the road then running as the car approaches. All tests were done with cruise control set to 40 mph. This is because the video reported the car travelling at roughly 40 mph.
Test one was the most surprising to me. It plowed right into the deer. It did see the deer. Watching the go pro of the dash it identified it as a car before flashing the warning sign and starting to slow down. But it wasn't enough.
Test two was also surprising. It slowed down considerably more when the deer was moving. Even though it didn't hit the deer this time it did result in the car slowing down to ~20 mph. Possibly enough to save the deer and or the car?
Test three was also surprising. Same result as test two with the car slowing down considerably.
I think overall the conclusion to draw from this is:
1) I have a strange sense of humor.
2) Eyesight should not be counted on in these scenarios. It is not a self driving car. It is not autonomous.
3) Eyesight could possibly reduce the damage to the vehicle and the deer (or other animals... or people) even in these extreme scenarios.
