Eap 2.5 vs 2.0?

According to Tesla:
“The internal name HW 2.5 is an overstatement, and instead it should be called something more like HW 2.1. This hardware set has some added computing and wiring redundancy, which very slightly improves reliability, but it does not have an additional Pascal GPU.”
Right, as far as anyone knows, there is no discernible (external) difference between 2.0 and 2.5 cars. In fact, without looking at the manufacturing date (sticker), you’d not know the difference.
they did state as one of the specs for hw2.1 that radar unit had a lot more definition. this is why i was expecting much better behavior under bridges, around trucks. so if you have some experience, chime in.
i do agree that between 2.0 and 2.1 the differences are minimal but could it be what makes all the difference in the world?!
probably not. question still stands.

probably not. question still stands.That's not really relevant in present day when AP2 is suffering day to day from a lot of false radar-triggered phantom vehicle / overpass braking events. And in the last 4 updates, seeing Tesla play a lot with turning on and off two-vehicle-ahead radar distance control. And the predominant change in AP2.5 was the switch from Bosch to Continental radar which led to deactivation of AEB temporarily.
I find it curious too whether or not the Continental radar behaves any differently from the Bosch units we have. It's curious that they switched suppliers especially considering Bosch is one of the biggest suppliers of automotive radar and Tesla was only using their medium line product.

HW talk? I'll bite.
I've wondered about that too, but then I came over this Nvidia PX2 info:
HW2.5 capabilities
Remember HW2.5 isn't just new radar, e-fuse and backup-cam wiring: There's a new autopilot ECU ("supercomputer") as well. We have some info from @verygreen on this, but not enough to conclude wrt exact product, this we need another @kdday-style teardown for

FWIW, I'd take that with a grain of salt (regarding specific radar models). After all, Tesla has clearly gotten the PX2 platform to work with the Bosch MRR14 even though it's not listed as a supported model. If they are buying radar units for at least 25k cars per quarter (not counting the model 3 at all), the engineering cost of writing a CAN-BUS driver for Autopilot is trivial. Every manufacturer expects some reference code to get started and do proof of concepts, but I wouldn't read too much into reference code supported peripheral models …
But yeah, I agree, HW2.5 has additional hardware, but it doesn't seem as likely that they play as much of a role in deactivation of AEB compared to the radar.
FWIW: AEB Pushing to AP2.5 today -> Tesla sticking with releases every 14 days
False ghost braking still exists on AP2.5.
