What is your point? Article says that it "makes no sense", I provided two counter examples. ICE cars also have batteries, if that gets flat, car is not going anywhere. Solar panels can be quite essential, if vehicle is parked for extended periods. It is not just some rounding error!

RVs also generally have spare tires, fridges, microwaves and beds! Why doesn't my sedan? Tesla needs to release a Model S with a microwave, fridge, spare tire and bed!

  Again! Trickle charge from solar panel extends battery life of internal (part of ICE) lead battery. This battery slowly discharges from internal resistance, other electronics (car alarm), GPS spyware... That means less batteries, less lead in nature, more green stuff, happy Gaia... And even EVs like Tesla has slow discharge. It makes sense to put small solar panels on top, so they can do firmware updates. https://hackaday.com/2020/03/10/solar-panel-keeps-car-battery-topped-off-through-obd-ii-port/ https://hackaday.com/2020/03/10/solar-panel-keeps-car-batter...

    It makes sense on EV for the same reason as ICE. There are any number of devices in a car that are always sucking down some small amount of power. Alarm/security/camera systems for example. Clocks and chips that store settings. If you're gone for a week you'd rather not have your battery go down.

      There’s a device for that called the Norelco Genius 2D. It is suitable for permanent installation in your car on the premise you have access to an outlet. It costs $50. If you have street parking only it is questionable whether you will be able to leave a car a whole week without incurring the wrath or a municipal agency. If you have parking lot parking only in an outside lot at an apartment complex of some sort, you might prefer a panel, though I more that you can get a kind that you leave on the dashboard that plugs into the lighter socket for a similar price —without the convenience of an integrated form factor admittedly but still.
