In a latest comparability of Tesla’s Full Self-Driving (FSD) model 12.5 on {Hardware} 3 (HW3) and {Hardware} 4 (HW4), Tesla homeowners Zack (@BLKMDL3) and James Locke (@arctechinc) examined the techniques’ efficiency on unprotected left turns (UPLs) and velocity bumps, revealing various outcomes.
Tesla just lately began rolling out FSD 12.5 to HW3 autos, after a month delay to accommodate for the older {hardware}. A large launch has but to occur.
In the course of the UPL check, Zack famous that his HW3-equipped 2019 Mannequin 3 (FSD 12.5.1.5 by way of software program model 2024.26.20) carried out properly, cautiously creeping ahead and taking the primary protected alternative to proceed. That’s what everybody would need for an autonomous system.
In distinction, HW4 on the 2024 Mannequin 3 (FSD 12.5.1.3 by way of software program model 2024.26.10) hesitated regardless of clear site visitors, requiring handbook intervention to proceed (he needed to press the pedal). Zack acknowledged that this is perhaps an remoted incident, suggesting extra trials are wanted.
When tackling velocity bumps, each {hardware} variations struggled, significantly with block-style partial velocity bumps. Zack’s HW3 slowed down just for the second of three velocity bumps, whereas HW4 exhibited odd habits, slowing down after already crossing the primary bump however ignoring the others.
As for auto set velocity, Zack noticed that HW4 tends to drive sooner than HW3, which frequently stays beneath the velocity restrict.
Try the movies beneath:
Right here is one other again to again comparability of FSD v12.5 on HW3 and HW4/AI4 with @arctechinc Mannequin 3 and my Mannequin 3.
This time we’re doing UPLs and velocity bumps with VERY attention-grabbing outcomes.

In the course of the UPL, HW3 did an important job, creeped ahead to see either side of site visitors… pic.twitter.com/UDC1vJmIoE
