Diggy diggy hole!
Nope. AirPods.
I went to see a doctor today because I've been having diarrhea and bleeding for 2 months, based on my symptoms and the test results he thought I probably have ulcerative colitis but need to get a colonoscopy soon to confirm it. Will call the clinic tomorrow to schedule it. I also got a prescription for prednisolone so that should hopefully help with the symptoms a lot. I haven't been able to sleep or focus on anything because I need to go to the bathroom like every 2-3 hours. Can't wait to get a full night's sleep again.
It's all fun and games until you end up stuck on an ancient spaceship billions of lightyears from home because you accidentally blew up the planet.
It's cheap and reliable.
It's not just about speed and acceleration. It's also about control. Racing drivers face an infinite number of different conditions out on the track and it would be impossible to tune the transmission in such a way that it does exactly what the driver wants 100% of the time. And it really has to be perfect. 99.9% isn't good enough because the other 0.1% can wreck the car if it does something unexpected while driving at the limit.
What difference does it make if the temperature is 79 or 80 F? That's a difference of about half a Celsius, and as a Celsius user, I can tell you that I don't plan my daily life based on a half a degree difference, or even a one degree difference; 5 degree precision is almost always enough.
The seatbelt isn't there just to keep you from flying through the windshield in a crash. It also keeps you in the proper seating position so you can reach the controls at all times, and reduces fatigue because you don't need to brace yourself as much when going around corners or over bumps.
I hope you realize that floating objects generally orient themselves in such a way that the most buoyant parts are at the top. So while you could float around, you would be hanging by your balls the entire time...
