    As pointed out already, acceleration here is massive, as collision takes split seconds.

    A more useful formula is: F=m*∆V^2 /2, where F is the force, m is mass, ∆V is speed difference (essentially your entire speed if you’re gonna hit the wall, and that’s very likely).

    Notice that speed in this formula is squared, so doubling the speed results in four times the impact.

    22% higher speed leads to 50% higher impact.

    41% higher speed doubles the impact energy.

    Etc. etc.

    Also, mass of your car, even though it’s not squared, impacts the result greatly. Twice as heavy car will exert twice the energy at the same speed.
