I disagree, there is more to steering feel than downforce, and the slower a vehicle moves, the heavier the steering would be, up to a point obviously (moving a road car steering wheel when stationery, feels very heavy, and the wheel going light at high speed on a motorway. Obviously the lightness is caused by lack of downforce but my point remains, there should be progressively more ffb, not none and then suddenly arriving when high speed occurs.
Some cars have lighter and/or more numb feeling steering at low speed that weightens up and feels much better as you get up to some decent speeds, and some cars have real heavy steering at low speeds which lighten up as you get up to speed.
Then on top of that, downforce can really have an effect aswell and in some cars you can really feel the downforce acting on the steering.
Like everything in physics, its real complex, and not just black or white, or one way or the other. It matters on lots of different things, for example power/no power steering, car setup (especially caster, camber), the actual suspension layout and design philosophy itself, different types of power steering systems, etc.
Did you know that mclaren made around 5 complete redesigns of its 2005 f1 car's front suspension just for Montoyas car? Montoya was having issues all year long with front-end feel, there was nothing wrong with the speed and design of it, but the different Fr-susp layouts can massively change the "feel" you get from the car. Kimi Raikonnen wasnt having these problems.
Also, this season, kimi raikonnen was getting Renault to make entirely new power steering systems for him all during at least the first half of the season, because he was having big problems getting the feel/feedback he wanted, and just like Montoya in the case above, he wanted a much different feel than the car was giving him. Roman Groj. like Kimi in 2005, wasnt having these front-end "feel" issues that there teamates were having.
So ya, front end feel/steering feel can differ massively from car to car, setup to setup, suspension design/layout to suspension design/layout, and power steering system to power steering system (the last 2 being highlighted in montoya's 2005 and kimi's 2012 cases).
