So I'm a total noob at physics but I disagree with your claim about acceleration being more measurable than speed.
Being pressed back to your seat is a consequence of the car seat being the source of the force that is making you accelerate while the force is not being distributed to each of the particles (that you are composed of) at the same instant. If the car was transferring that same force (like magnetically or something) to each of your particles uniformly then you wouldn't be noticing the acceleration as there would be no compression happening within your body.
Maybe there is some other effect that happens during acceleration that could be used to determine acceleration is taking place? I'm trying to think in terms of a single electron or neutron or something for simplicity. Not coming up with anything so far.
