MSFS team please restrict cars and fork trucks from driving on the runways. Kills immersion!
Were you in Gibraltar? 
I saw this in the Houston airport, George Bush International, felt like a highway was coming through the taxi lane, lol.
Not Gibraltar, I was somewhere in the US .. this is a coding problem.
I saw that the KIAH (Houston) has well. The road goes under the taxi way in real life. In the sim it goes right across the taxiway.
Same in EDDM
