My guess is that either the driver's vision will be quickly impaired or his/her eyes will quickly start hurting. In that case, the driver will quickly know something is wrong even if he/she may not know it's an attack.
I'm no expert on laser safety or human biology, so I left a question on biology SE: http://biology.stackexchange.com/questions/38603/how-quickly...
Hopefully somebody can give an answer.
And if the driver experiences no symptom, then the attack is just ineffective.
