So, the cause was cold tyres causing the car to bottom out, not the car being inherently difficult to drive? Cars crash at Tamburello, but not because they are hard to drive, but because something goes wrong; whether low tyre pressures, broken steering column, broken suspension, or whatever. Just ask Nelson Piquet, Gerhard Berger, Riccardo Patrese (or look at Michele Alboreto's testament).
Yes, Senna was worried, but the biggest worry was that the cars had out-grown the circuits! He actually looked at the wall at Tamburello before the season, as he was worried that there was only 10m of run off, and in recent seasons, Alboreto, Patrese, Berger and piquet had all had major shunts there (when something broke in each case)
To say that today's cars would be undrivable without driver aids is completely lacking in context; look at the monsters that raced in 1987-1988. These cars had over 1000BHP... No traction control, manual gearboxes, etc., yet the drivers weren't constantly killing themselves!
In much the same way, when traction control was most recently banned, people were claiming that drivers would be spinning off all over the place; what happened? Sweet FA.
Driver aids were not introduced to make things safer. They were introduced to make the cars go faster. When all the cars has the same driver aids, then there's no point in having them! Are you going to tell me that there's a particular safety reason why drivers now have an audio cue to change gear? I mean, WTF?!? Drivers are not driving unaided... They have about 10,000 times the processing power of the Apollo moon landings also helping them along the way!
Get rid of all the engine settings, get rid of all the fly by wire, introduce manual gearboxes, reduce the grip from tyres, and I guarantee you will get great racing!
