Model 3 HW3 retrofit questions, wait time, issues

[RayK]

@PhysicsGuy Okay, here's more doom-and-gloom stuff that may happen with the HW3 upgrade than what I first indicated:

• The tech screws up something awful and bricks your car
• During installation (or maybe sometime after) the cooling hose the new computer taps into leaks fluid
• Personal info stored in the old HW2.5 system somehow gets onto the darkweb and you get hacked
• Camera recalibration does not successfully complete and you can't access EAP or FSD functions (and maybe TeslaCam doesn't work either)
• A nagging rattle develops under the dashboard

The possibility that any of this will happen to you? I'd say extremely remote. But I equate the HW3 upgrade to what you might encounter/expect when replacing your old, slow CPU in your computer or laptop with a version that's newer and faster. Also, when taking something complex apart, there's always a chance that Murphy's Law will be invoked.

Sorry to hear that. I tried to help spare some folks that grief, but the trick is they need to read this before picking their post-operative patient:

Model 3 HW3 brain replacement can cause temporary amnesia but Tesla Service can quickly restore your settings, all you need to know before you go

PCs, EVs, home tech, efficiency, and more.

FYI, when they did my HW3 update it was seamless/flawless. I didn't lose settings and nothing went wrong from the upgrade.

The new visualizations are nice, and looking forward to vastly improved city FSD behavior soon.
