Only if you're an emergency vehicle and have a loud siren.
But as I observed only yesterday, sometimes not even that works. (Fire engine held up by MMs who had no idea it was 25m behind them)
The problem is rarely visibility. And the "bike ninja on an unlit road at night approaching a t-junction" is the exception that proves the rule.
The main problem is drivers who don't look, or won't look, or can't see (A-pillars and mirrors), or who are travelling faster than their brain can process events (i.e. speed limit is set too high and we-have-to-drive-at-the-speed-limit-you-know).
Or who drive too bloody close even though they know you're there.
This is how cyclists, pedestrians and trees "come out of nowhere".
