IMHO, as a private pilot, this is journalistic sensationalism at its
best (worst?)!  A few points:

-Although I don't have data, ground collisions are pretty rare.  A
Korean DC-10 / commuter at ANC, a TW(?) / private plane, the Tenerife
accident, a ground near-miss NW DC-10 / NW 747 at MSP, and a TW / NW a
few years ago in the Midwest were all in broad daylight.  The USAir 737
/ Wings West accident at LAX was at night, but in an area not visible
from the control tower.  Seems to me daylight ground collisions are more

-  Road vehicles don't have a lighting system to clearly identify what
type of car they are.  What would be the point?

-  Major airports have ground radar which aids ground ops especially at
night and low-visibility.

- Runways are marked with "hold bars", lighted signs, and alternating
flashing lights to clearly identify hold points.  You cannot proceed
past a hold point unless instructed to do so.

-  When taxiing, be assured the pilots are not blindly following the
ground controller's instructions.  They are also looking out the
windscreen for potential collisions.  I don't know any pilot who doesn't
double check before taxiing onto an active runway!

Hope this puts your concerns to rest.
