One of the disadvantages of residing in "up-market" Parnell is that public events occasionally occur in the adjacent Domain, resulting in a cacophony that tests sweet reason for those living close by.
This week it's been rally cars snarling around the Museum.
I appreciate that viewing the reigning international champion driving flat out in his diminutive Citroen is intoxicating for petrol-heads, but why are today's rally cars so damn noisy?
It wasn't always so. In my own rally-driving days (hard to believe folks, but sadly true) variations to specifications for competitive purposes consisted of a few extra spotlights on the front bumper, plus a shovel tied to the roof to dig one's way out of snowdrifts and mud on mountain roads.
I don't recall my genteel Sunbeam-Talbot ever waking up the neighbourhood as we sped through the night on time trials - and before you laugh your head off at the thought of this sedate, granny limousine having any sporting inclinations, check what won the Monte Carlo Rally in 1955.
