Runway incursions are very serious things. Although it may not sound like it, what if the fact that the vehicles where there was not known until too late...airliners slamming into large heavy objects at takeoff/landing speeds is not usually a good thing.
I'm sorry if I sound pushy about it or anything, its just that us pilots are very concerned about runway incursions and they happen all too often. Luckily though, they often end up without an accident.

Runway incursions are extremely dangerous and can never ever be dismissed as "no big deal". It's all about safety off-course. I do not need to remind anyone here what happens if a large transport aircraft hits a car or whatever at 100+ knots [remember Tenerife KL/PA, remember Taiwan SQ].
Runway excursions can NOT be dismissed as something like an engine failure. I mean engines are designed not to fail. But once and a while they do. Therefore all transport aircraft are required to have at least two engines. When one fails, there's a back-up system. Basically this is the case with everthing in aviation. If one thing or system or procedure fails, there are other things or systems or procedures that will provide a satisfactory [but reduced] level of operational safety.
In a runway incursion, no matter how innocent [if possible at all...], ALL things or systems or procedures have failed, and the only reason that no serious accident has happened basically is pure luck. This is not were we want to be in aviation. It's like a dual engine failure on an A330 over the Atlantic ocean. You're out of options. A runway incursion means that ALL line of defences have failed. Therefore a runway incursion is extremely scary.

Runway incursions can be a big deal.
To bring the example a little bit closer to home, I recently had a vehicle vs. deer accident. My car cost me about 24k when I bought it around thanksgiving of last year.
I was going 40-45 in a 55, accelerating from a stop light, and a deer ran out in front of me, 6300 in damage to my car. So basically that deer is costing my insurance company about 25% of what that car is worth (minus my deductible of course). Now, let's move that to this incident, even if you compare apples to apples (which is impossible to do), well, you can imagine what 25% of a 777 costs. And if the accident had happened, I imagine it would have done more than 25% damage.
