From the website, the ramps appear to be about 5m long. So using v^2 = u^2 + 2 a s, we can find the deceleration. This works out to about -1.6 m/s^2 or about 0.16g. 1g deceleration is what you would see in a high performance car under maximum braking. 0.5g is nearer the mark for a standard car. So a third of this is a SIGNIFICANT deceleration. This will cause aggravation, to say the least.
