Not in low orbit or lower. We'll see how planetary landings play out but they'll have to re-write normal space flight mechanics a bit because ~300m/s is well below escape velocity for earth and the FSD should be mass-locked at sea level.
At CONSTANT thrust you can achieve escape velocity at 1m/s. Will take a very long time though.
For planetary landings, either they lower the minimum SC velocity to 8.2 km/s (Space Shuttle re-entry speed) or hand-wavium facts that ED ships have stronger shielding. 30 km/s is the average speed of an asteroid/metorite and they break up on entry.
For planetary takeoffs, 300 m/s is way too slow, would take approx 24 minutes to just get to ISS orbit distance of 431 km. So FSD will have to be re-jigged for takeoff.
Space elevators go upto approx 36000 km, geostationary orbit distance. That would take approx 33 hrs and 20 mins at 300 m/s.
Still would like to see a few space elevators though. They would have their purpose as cheap hotels for those who can't afford to get to space stations. Also as a simple way of getting cargo down to the planet without the need of a ship.
