Not trying to add to any discussion about a any specific combo selection. Just throwing out some SNAIL history and an opinion that has been formed after years of observation.
This is a list of the 10 most used cars in SNAIL history. Most of them are from previous games but the general idea has always been the same.
Lotus Elise Race Car '96
Amuse NISMO 380RS Super Leggera
West Surrey Racing, 1983 Ayrton Senna
Caterham Seven Fireblade '02
Amuse/Opera Performance GRAN TURISMO 350Z RS
Mazda RX-7 Spirit R Type A (FD) '02
Acura NSX LM Race Car '91
Lotus Elise 111R Race Car '04
Gran Turismo Racing Kart 125 Shifter
Ferrari 430 Scuderia '07
Most of these cars have something in common. They are easy to drive. Maybe even being boring to drive alone as they are pretty well planted to the track and don't have a tendency to step out unless you do something terrible wrong. These types of cars allow more drivers to get closer to the limit performance out of the car which leads to drivers thinking more about racing and less about just trying to keep the car pointed the right direction.
Some of these cars have produced the best racing in the history of SNAIL. I'm reminded of the races with the Elise Race Car at Grand Valley. Week after week of nose to tail racing with multiple position changes in a lap. It was great stuff and it was possible because the majority of drivers across all divisions could easily control the car on multiple lines around the track and concentrate on making passes for position.
On the other end of the spectrum, I am reminded of the TVR Speed 12. This car was chosen and ridiculed and the defense was that it was a challenge to drive and if you didn't like it, you didn't want to get any better. The car was raced and it was voted off in resounding fashion after one week. All the effort from the driver went into trying to keep that beast on the track and actually racing it was just about impossible. The car was great fun to try and wrestle around the track on your own but it just didn't race well.
I have seen this pattern work both ways for years now. Combs that race well and allow drivers the chance to focus on making moves rather than staying on track seem to last longer than combos that, while fun and challenging to drive alone, force the driver to concentrate more on staying on the track rather than where the next pass can be made results in combos that don't last long at all.
That's the end of my PSA for today. If you read it think about it and either apply it or don't. At the end of the day, if you win a prize, it's your's to do with it as you wish.
