Absolute ground speed record (More than the third space speed by FOURTEEN times!)

Using horizontal 300 tons of thrust (a mod by Agent Y) and a vertical thruster for 5 tons, I was able to accelerate to 860 thousand kph in an hour, moving with a constant horizontal overload of 10g.



The question is, has anyone traveled further or faster?

If necessary, I will attach here a link to an hour-long video of how such a speed is achieved and what happens to the car with this time. Environment settings are standard, gravity too

 

almost 1.8mln mph
