What sort of car are you talking about that still has a dizzy?

most do. Or many do. No contacts but still one 25kv coil feeding one of
four (6 or 8) plugs..via a rotating rotor arm. there may also be a
sensor there to monitor crank position. But thats more generally on the
camshaft

As is the distributor itself sometimes. Depends really on packaging.

I ask again. Name one new car with any form of distributor. If one exists,
avoid it. As it has an ancient engine design best left for the science
museum.

All of them. Without a distributor you need at least one coil per
sparkplug, unless you want to take the risk of firing all the plugs all
the time and the possibility of a misfire ..

On a 4 cylinder you use double ended coils and fire both. No need for
*any* distributor, just a simple sensor on the crank or cam.
