English ivy is a ground spreader, at least where I live. It won't grow on the ground if it gets a lot of sun, but ground shaded by trees will turn into a thick mat that is impossible to pull up. Some yards have it growing as a ground cover in the flower beds. You can't pull it off walls or the ground easily. It grows tendrils (roots?) into anything porous, which makes it extremely difficult to pull up. If it's growing on the ground, it's just a thick mat that is impossible to pull up. And while I wouldn't call it a fast spreader, if you ignore it for a couple of years, it will start to take over.

I've sold lots, some of which were obviously chopped out of vehicles with a sawzall (vehicles that I legally owned, btw). They've always scanned my ID, took my thumb print, and mailed me the check after a couple of days.
I had a math professor who I'm pretty sure was borderline autistic. His son actually was autistic. While he wasn't the best math teacher I've ever had, he was very good. (Didn't help that I can't comprehend delta-epsilon proofs.)
That was true 20 years ago. The question is how much do you ease up the brake on that specific wheel, and then how much do you reapply it? You need to know the coefficient of friction of the road to know this. Modern controllers are doing a physics simulation of the entire vehicle, and part of this is the weight transfer as you go around a corner (which is partially influenced by the CoG). They then do a physics simulation of the hydraulic brake circuit so it knows how long to run the pump to build up the desired brake pressure.
Now of course this is combined with stability control (since that is required by law) and both of them are controlled by the same code.
(On a related note, I've spent way too much time reverse engineering the calibration for the ABS for a Silverado truck. Ridiculously huge program, ridiculously complicated, and I have a sneaking suspicion that the source code is a mess.)
Or, like my wonderful neighbor, want to remove their muffler to show off how awesome they are.
More seriously, a successful electric car needs a chassis that's been engineered to be an electric car. You can convert a normal front engine, rwd chassis, but it's always a compromise.
> and a software patch that lets a driver know if their brake fluid reservoir is running low.
You mean like every single other vehicle ever made? I thought this was a law. Also, if all it takes is a software patch, then that means there already a fluid level switch in the reservoir. Unless they are doing some magic computation that measures the brake fluid pressure and the brake pedal position that's able to detect air bubbles in the line. Modern ABS controllers are already doing a full physics simulation of the hydraulic brake circuits, so it's possible.
I have a family friend that recently had 2 strokes. The doctors are confused because he has none of the risk factors for a stroke. Really, he pretty closely follows this: (https://news.ycombinator.com/item?id=32143344). However, he's been practicing breathing exercises for years and his resting heart rate is ridiculously low.
My grandparents bought a game camera at Costco, so they could see what animals were in their yard at night. I had to help them view the pictures on the SD card. It came with some app to view them, or you could just stick the SD card into any laptop. Figuring that was the easier route, I opened up my grandma's laptop and gave them instructions on how to insert the SD card, open Windows Explorer, navigate to the D drive, no wait sorry now it's the E drive, open DCIM, right click here, double click, now single click. 5 minutes later I realized how fucking stupid this all is and installed the app on her tablet.
Perhaps. But that's how Starbucks works, by buying shitty beans and dark roasting them. It also makes it easier to have consistent coffee (consistently burnt, that is).
