The LZB continues to work after leaving its coverage area. I am already 20 km from Fulda, still driving under the LZB. 0_o Whoa. After i post this it stops working and gave me 1000 Hz indicator. Maybe it awake after I've pause the game. Now I got endless 1000 Hz indicator, which is just a visual, cause I run 160 kmh without any consequences. It was eventually stopped glitching by proceeding over actual 1000Hz magnet. What a great glitch!
