Going off of SMCF, it really depends on how liquid you are and what country you're in.
If you're in the US, I have SoFi and 4.5%/APY on my savings account. Gotta have your direct deposit or move $5k monthly into the checking. If you can swing that, it's a great bank. I think Ally does similar.
Most major brick and mortar banks are shite for accruing interest money.
Going off what fishpen0 said, Waymo actually has sensors on it to detect things and can "understand" its surroundings much better than Tesla cars can wish just cameras.
I've ridden in Waymos and they are smooth riding. After the initial "OMG! There's no driver!" You kind of forget about it. You get to your (limited area) destination safely and without much hassle.
I can go more in depth if ya want.
