At least all the Toyota and Mitsubishi electric prior to 2018 or so. And I did not even look up anything in particular, it's just well known that none of those had any kind of remote upgrade.

I would advise you to do longer pauses when you are on such a long trip (not only me, the road safety specialists too). It's not for the bladder, it's for the fatigue, particularly of the central nervous system.

The risk is not to be killed by a bladder shrapnel, it's to switch off the attention and be crushed by an unnoticed lorry.

Could you name one in particular that has this range?

A six hour drive is "such a long trip"? You need to extend it to eight hours to make the road safety specialists happy?

About road safety: Yes. Seriously lol please put a bit of your own energy in searching this.

And it's not "to make the specialists happy", it's to increase safety according to the knowledge accumulated thanks to such specialists.

(ok I see "neo-luddite" in your profile, but usually that does not entail "not trusting scientists/specialists")

You have a flesh brain like everybody else, with biological limitations that lead to fatigue and decreased attention after a long drive without sufficient pause.
