Hot as hell here in Aus. 41deg C the other day. T-shirt and shorts as well, or drive a car.
All a bit moot, since the original poster after nearly a month hasn't replied to anyone.
Would love to get to those Italian Alpine roads,
I know what you mean about heat!!! I live > 1200km from those Alps and during summer we have our good dose of heating from the Sun and from African winds. But usually we say better safe than sorry and in case of an incident – I suppose our traffic is a little worse than yours – having long pants, jackets and maybe gloves can help. That's the ratio of my reply.
I meant no attack to you or your ideas … and if I was rude I am sorry !!!!
English is not my primary language and maybe I used wrong words…
