I'm puzzling over whether those comments are about this bill as written. Here's a few bits if it:
(1) A person commits an offence if—
(a) the person shines or directs a laser beam towards a vehicle which is on a journey, and
(b) the laser beam dazzles or distracts, or is likely to dazzle or distract, a person with control of the vehicle.
...
(6) In this Act “vehicle” means an aircraft, motor vehicle, pedal cycle, train, vessel, hovercraft or submarine.
(7) In relation to a motor vehicle or pedal cycle, the reference in subsection (1)(a) to a journey is to a journey made on a road.
(8 ) In relation to an aircraft, the reference in subsection (1)(b ) to “a person with control of the vehicle” is a reference to any pilot engaged in controlling, or in monitoring the controlling of, the aircraft.
(9) In relation to a vessel, hovercraft or submarine, the reference in subsection (1)(b) to “a person with control of the vehicle” is a reference to the master, the pilot or any person engaged in navigating the vessel, hovercraft or submarine.
(10) In this Act—
“aircraft” means any thing used for travel by air;
“motor vehicle” means a mechanically propelled vehicle intended or adapted for use on roads;
How wide is that? It leaves out a vehicle controlled by a person not carried by it, or by machinery - though that could still be dazzled. It looks as if it only addresses vehicles that do carry people, irrespective of how big they (meaning the vehicles) are. The few things left out entirely (sledges?) are probably not common enough to worry about.
But remember that the wording is likely to be gone over and altered quite a bit, and will and up sounding a lot more "legalish" by the time it escapes.
