Do you even use GetVehicleVelocity before putting the player in the vehicle? because in your current code xVel, yVel and zVel appears to be 0.0 0.0 0.0 .. and don't set the player's velocity after putting them in the vehicle, thats a waste.
And try putting them in as a driver then settings velocity then putting them in as a passenger
