However, seeing it from the "grumpy old g1t" viewpoint, the recent outbreak of tints and SUVs/Crossovers have undermined the usefulness of the mandatory high-level brake-light. If you are behind a car with heavy rear-screen tints, or any 4x4 or lookey-likey, it's no different to travelling behind a bus. Safety advantage gone, drop back and increase length of traffic queue.
And at two-lane junctions on to main roads where you are turning left and the motor next to you is turning right or going across, it is becoming increasingly common to have to wait until the other car, of type described above, has departed (and hope the next bugger in the queue doesn't have a van or creep forward too far) to get a safe view of the traffic. The departure junction from our office is like this, and I find myself on occasions waiting a couple of minutes to get out, during which time no traffic has come along my side, but the other s0d has blocked my view...
