Roadtrip - Mulhouse to Geneva road advice

[JB65]

Morning all,
Planning our 2021 road trip for a group of 6 avid drivers (911, Vantage, California). Having covered most of the Swiss and Italian Alps we are heading for the Voges and Route des Grande Alpes this year.

For trajectory Mulhouse to Geneva - am looking for suggestions on worthwhile roads that lead west from Mulhouse and lake Neufchatel (rather than straight Motorways through Switzerland)
As always your help appreciated!
best
JB

No advice on the road but make sure you don’t just walk out of the museum and miss the classic car rental at the track at the back , you get 7 laps in the car of your choice for €50 - €100 , or at least you did a few years ago . You can also hire them for an hour or half day to drive on the surrounding roads , again , you used to be able to when we visited . We drove the c1 corvette and the Porsche 356 roadster for a laugh though I believe they have a much better selection available now . It is easy to miss on the way out as it just looked like a car park .
