Very good!  I just managed to win the Championship on Easy mode  :-)

The thing is, I can actually recognise the corners from the real tracks.  Especially Monaco, and Spa's Eau Rouge.

That's a good improvement :-)  Thanks for the update.
I'm still getting score problems, though.  I've uploaded a temporary unlisted video so you can see it (see the video description for the examples):

Also, I don't think I've ever had a fare to the Hospital, even though it's a named place on the map.
When you lose your last life it says "You taxi medallion has been", then cuts off to show your the game over screen before finishing the sentence.

Not bad, but seems like the original programmer didn't finish it.  You only get score for moving, and getting to the top (any part) just starts another frog and gives you an extra life.  I quickly got 9 lives and just kept going until I got bored.
It's a shame, as it's actually mostly there.  It just needed finishing off.  At least you got it working on more models.

It runs well on my PET 4032.  A few comments so far:
There is an invisible wall left of TPUG that stops you going up/down.
With messages off, it doesn't tell you to press Space to continue when you lose a car.
A personal thing, but assigning the keys is in a strange order.  The first go I expected it to be up, down, left, right, and ended up with my keys all wrong.  I should have read it and I'd have seen it was up, right, down, left.
It mentions smoke, but I couldn't find any.
It could do with a bit of sound, even if it's just a beep when you collect people, drop them off, or crash.
The score seems to go wrong when you finish a level.  I had 960, then when I started the next one I had 110.
The destination said "6)7EB)8EC)" when I picked up a fare (it ended up being Slay Radio).
It's odd that your score goes up the longer you take (though I suppose that's how Taxis work), but I suppose you have to decide if you want to risk running out of fuel.  I couldn't find a petrol station, so I assume you have to try to finish it going really slowly once you run out.
I started to capture some video for YouTube, but if you think you'll fix the invisible wall, and maybe add some sound soon then I'll wait and put up the improved version.

I'm not a Mario fan at all, but I really like this.  Much more fun for me than the original because Mario isn't in it!  It plays great, and I love the auto key configuration.

This is great.  Another excellent PET game  :-)

Is there a way to end, or do you have to get killed to end the game?  I rescued them all then was just flying about until I deliberately got shot to end the game.

Excellent update!  Well done.

It works great on my 4032.
