Dollars to doughnuts it's not about the billboard or the Ford [Q-team] is in.
It's all about the driver/passenger in the white car.
To me it looks like a picture taken while traffic was stopped, perhaps at a red light.
The 'qresearch' board is becoming so mainstream (and we know black-hats tune in) that I wouldn't put it past Q sending a RT message to the other occupant, who could have discovered the picture shortly after the traffic started to roll.
Would be a scary message to someone on the lam.
We see all…we hear all…
You can run but you can't hide.
‘We can take you anytime’
‘We can hear you breathing’
