it takes a lot of extra energy to move that extra mass

You'd think so, but it actually doesn't. It takes more energy to accelerate a heavier vehicle, but an EV doesn't just use all that kinetic energy to heat up the brakes when you stop, it goes back into the battery.

Cars don't propel themselves by generating thrust, and hydrocarbons are enormous. Were you thinking of aircraft and hydrogen fuel cells?

That's because synthetic, renewable fuel is usually used as an excuse to take no action and keep burning fossil fuels rather than an actual plan for the future. "The future is synthetic fuel! ... and it's coming like really soon now and totally won't be impractically expensive, so let's all keep using combustion engines and fossil fuels."

The absurd efficiency means electrification is the best solution unless it's something batteries can't do, like carry enough energy for medium and long distance flight.

However, most cars are used in cities while rural and distance travel is a small fraction

Yes, the vast majority of driving is short distance, but people who are buying a vehicle will want one that covers all of their usage. That's what fast chargers on the highways are for - they make those occasional long trips slightly slower, so owning a short range EV just means one or two more charging stops per year instead of being unable to do it.

Variable refresh rate support is incredibly important for making games feel smooth at lower frame rates, so it was always a head scratcher for it to be missing from handhelds. With VRR you don't suddenly get stutter or tearing if you fall below the screen's refresh rate, so there's no need to fiddle with settings to keep the game running at the screen's exact refresh rate at all times. The refresh rate just follows the game's rendering speed on the fly and dropping to 53 FPS feels the same as solid 60 FPS.

LFP batteries already solved that a few years ago. The lower cell voltages means they can use a more stable electrolyte which doesn't break down and produce oxygen at high temperatures, so thermal runaway and the cells going off like fireworks isn't a thing. Damaged LFP cells get hot and then just slowly cool down again without fire or setting off other cells. They just stop working.

PHEV is the easiest drivetrain to live with in a daily basis.

Well, it depends on your usage and situation. If you have home charging, you only need public chargers if you're driving more than your vehicle's range in a single day. With a modern 250+ mile EV, some people would only use a public charger once or twice a year. So it winds up being easier and less time consuming than taking your car somewhere to fill it up every week or two.
