Hi,
increasing the luxury, comfort and safety sliders should have a negative impact on a vehicle's weight as that should logically increase with added (abstracted) safety features and creature comforts. Vehicles are far too light right now, making it too easy to design very fast vehicles with comparatively small engines.
Also, top speed should be limited by chassis type or possibly other factors. Given a big enough engine, an early 20th century frame will easily reach Bugatti Veyron speeds - not realistic (maybe consider implementing some sort of tire model as well in this regard). IMO it would also be cool to have the option of adding a top speed governor for later years in order to cap top speed at, say, 250km/h like most manufacturers do nowadays. The in-game benefit would be increased reliability and maybe a better safety rating?
