Concept art and storyboards for the Matrix Reloaded.
The hovercraft have some basis in reality, if we imagine them to use ionic air propulsion (but at immense energy cost).

The Kharkovchanka was a Soviet off-road vehicle based on a T-54 tank chassis, meant to drive all the way to the South Pole.
Its 70 tons (with trailer) was propelled to an average 6 km/h at the cost of 10 litres/km.
There's also a good documentary on it:

The Extrasolar Object Interceptor is a NIAC-funded design for a 1 ton probe that can catch Oumuamua or Borisov with 100 km/s of deltaV thanks to an insanely radioactive 'atomic battery' based on Cobalt-60 and a 15,000s Isp electric thruster:

Speaking of better things to do:
-installing simple space mirrors.
-painting deserts white
-Direct Air Capture of CO2
ect.
None of these are as difficult or needs tens of terawatts of power!

Earth orbits the Sun at about 30 km/s.
The Solar Escape Velocity at Earth's orbital altitude is 42 km/s.

Therefore, the maximum relative velocity for an impact with a solar system object (asteroid, comet) is 72 km/s.

However, interstellar object can come in even faster.
