...Based on the email that went out to EAP owners today, one could reasonably conclude they're not going to provide Enhanced Summon to EAP owners. (Though I suspect that will not actually be the case, that's the way the email reads if you take it literally!) So maybe it's just too hard with HW 2.5!
I've seen enhanced summon on HW2.5 cars so it seems they are still trying. It does meet the "still sucks" criteria though. Lots of pauses with lock to lock steering changes. Goes 4 MPH. Misses the push pin placement by 20 feet or so. It does follow the owner like a dog though if one uses that mode.
