Yup. You're obviously familiar with air ops.
It wouldn't matter if the driver was drunk, stoned and on heroin simultaneously; if he was cleared at the same time as the aircraft, it's on the tower. Even if he wasn't cleared the tower should have had situational awareness.
In my experience, most airfield/runway snafus are caused by idiots in the tower. Then again, who knows how they do things in Russia.
I guess he should have watched that FAA video on runway incursions. I have to sit through that thing once a year.
