AP2.5 AEB performance

So, at least we know that Model 3 (is that AP2.5 hardware?) with Karpa-vision will automatically emergency stop from 12 and 25 mph, 19 and 40 km/h. That is the only test IIHS does. You can also get a full score even when bumping into the dummy.
Front crash prevention tests

EuroNCAP on the other hand tests speeds from 30-80 km/h, 19-50 mph.
AEB Interurban | Euro NCAP

The Leaf manages to avoid a collision in a stationary dummy from 40km/h and against a moving one from 70 km/h. Looking forward to the European tests to benchmark the Tesla system, as it seems the US test does not test the full potential.

Do you think these Model 3 results transfer to AP2/2.5 S and X also?

As an aside, I think in general, you have to take these kinds of tests with a grain of salt, because they are testing head-on against a previously agreed upon blow-up doll of a silver car or crash test dummy. You can expect every manufacturer to have developed and tested their AEB systems against these test scenarios.

In the real world, how do these test results translate to approaching a fire truck, or weirdly painted flower delivery van, or around a curve, etc? I wish someone would do more realistic tests.
