You could install a simple differential. The required bevel gears may be recovered from old angle grinders.

that is a good idea. there could be 2 versions. minimal version with compensating gear made of angle grinders. version 2 with car batteries and hub motor

Very quick and dirty, using PartDesign, FCGear and Assembly4, loosely based on this image from amazon.

Have you driven forklift truck?
Rear wheel steering at speed will be "interesting"
Good luck

..

that's how I see it, but if you drive a maximum of 30 kmh in the city, it should be safe

Interesting for sure, but real problems occur only if you have a negative caster angle.

update

Solar panels provide shade and charge during the journey and when parking (during the day)
