Yes, I live with the loss. It is actually beneficial and prevents the front-end of the SDR from overload since the majority of good SDRs have sensitive / high gain inputs. Most SDR receivers do not have band pre-selectors in the front-end so keeping overload to a minimum across the input is beneficial.

I tend to use mini-circuits splitters. Although the port loss is substantially higher (approx 6 dB per port) it is at least linear across all ports. Port-to-port isolation is high, typically 30 dB. For high gain SDR receivers, the 6 dB loss is marginal. For example, my RSPduo typically runs at +20dB IF input attenuation therefore the 6 dB loss of the splitter has no negative impact. If necessary, the loss can be mitigated by adding a good quality 6 dB amplifier at the input of the splitter thus keeping unity gain on the outputs. Just as the splitters, there are also suitable mini-circuits amplifiers available.
A ZSC-4-1 splitter gets you 4 ports, 0.1 to 200 MHz and a ZSC-4-3 gets you 4 ports, 0.25 to 250 MHz.
There are plenty of surplus mini-circuits splitters and amplifiers on eBay at a very reasonable price.

If you ask me there has been no foresight into this decision by certain auto makers. This may be good for large metropolitan areas but useless if you are rural. Where I live, there is no such thing as digital AM or digital FM so I guess, no radio at all?

According to the May 2023 edition of The Spectrum Monitor, WLO is back on the air.
Hugh Stegman offers the following schedule (c) The Spectrum Monitor:
H+0 -> 1 kHz top-of-the-hour audio beep followed by 3 note musical interval signal followed by an automated female voice “This voice-synthesized weather broadcast is brought to you by Global HF Net.” The length of the broadcast can run anywhere from 3 to 9 minutes, possibly longer and concludes with “This is the Global HF Marine Radio Net, station WLO standing by.”.
H+15 -> Interval signal and the same voice with “This is the Global HF marine and nautical radio system, part of the Global HF net.”.
H+18 - > Interval signal followed by “This public coast station is participating in scientific studies conducted by the National Institute of Standards and Technology. All stations please stand by for a test signal transmission. WLO testing.”. This is the same hourly test signal heard on WWV and concludes with “Station WLO, Mobile, Alabama, test, out.”.
H+30 -> Station ID, interval signal and “These voice synthesized marine broadcasts are brought to you by Global HF Net. This is public coast station WLO located south of Mobile, Alabama, just north of the north coast of the Gulf of Mexico.”.
H+45 -> Repeat of the H+15 ID.
