Still living in southern Ontario, and I see light signalling from other cars less often than I recall from years ago.

Indeed, flashing headlamps is not so simple anymore, what with Daytime Running Lights, HiD headlamps, always on headlamps, automatic headlamps, automatic high beam dimming, and general electronic 'helpfulness'.

HiD headlamps do not like to be flashed on-off-on-off-on and the slow start-up process precludes flashing them when off and actually having a noticeable effect.

General ignorance of the finer points of driving etiquete seems to have increased, while wearing my curmudgeon hat.
