This is exactly why I don't trust FSD in stop and go traffic. The follow distance is too close on some versions where it will accelerate hard and start braking around 10 feet. One misstep and that's a rear end. The latest version is better, where I feel more confident with it's easing, but there's constantly regressions where it goes back to an aggressive braking where I'm always afraid it'll rear end the other driver.
Are you using wifi? I have the 4850 and the wifi would sporadically drop out after a few hours and I wouldn't be able to reconnect without a full factory reset. It was the most frustrating thing. I was about to return it then moved it to another location and connected it via ethernet. It's been fine since, but a $350 printer that doesn't have a reliable wifi module is terrible. After searching on reddit, it seems it's a common issue.
I ran into a similar situation, but it was with UPS. UPS "lost" my package and it went back and forth between several locations. It was never marked as delivered, just forever in transit. I even got a call from someone claiming to be UPS to see if my package was delivered. I contacted Apple and the same thing happened, they couldn't do anything. Talk to UPS. UPS said talk to Apple. Both parties kept blaming the other party. UPS said internal investigation yielded nothing. I was telling them it clearly still said in transit and it's bounced around for several weeks. They said maybe it'll get there eventually.
I contacted Tim Cook's email and someone from the team responded and worked with me through the situation. Fortunately, we had a lucky outcome, and we got our payment refunded, but the entire ordeal took around a month and lots of calls to the CS/live chat support.
It would be eating smaller portions and less throughout the day. It'll spike anytime you have a meal, however, any five minute activity that cause sweat will significantly drop your blood glucose levels. Eating fiber, then protein, followed by carbs will flatten and slow down the curve.
Stelo (https://www.stelo.com/) and Lingo (https://www.hellolingo.com/) are the two non prescription ones. It's definitely worth it to try 2 weeks and see how different foods/environments spike you.
The issue is if you have FSD (beta) enabled and you attempt to yank it, TACC will still be engaged, which makes you drive straight. If they had lane assist on as well, it would essentially swing you back and forth. It's dangerous if you aren't aware of it since it suddenly goes from FSD to why does my car have a mind of it's own. If you ever see a Tesla on the highway frantically swinging back and forth, the driver is probably trying to disable the car and fighting with the other safety features. Hitting the brakes will ensure FSD/TACC gets disabled properly.
Note: Most of the time people are referring to FSD as FSD beta. Most videos you see online are FSD beta. FSD is still very dumb, but includes stop light awareness. FSD beta is what allows you to "self drive" in the city.
I'm in the same boat. I disable auto-lock. However, it would be nice to have a setting for 30 minutes or an hour, but thankfully my battery will die before that's needed.
Priority delivery fee is a scam on all services. If your order is sitting a while, it's generally because the $ to mile ratio is too low. A $2/mi order is considered a base line for most drivers. Orders will start with a low base pay of $2-$2.75 + tip. If drivers keep declining to pick up your order, it'll get batched with another order. Priority delivery fee goes to the delivery service, so you might as well put that towards the tip instead to get it picked up faster by a driver.
