Ditto... if it's over 100f... I'm in a long sleeve shirt (for sun protection)...
FF helmet, jeans, fingerless gloves, and ankle high shoes,.. but no jacket...
Just can't take it...
Leather will help some, with abrasion... armour will help a little with some bruising,.. but,.. it's mostly false security... 1/2" of foam won't do much against a car... Bones still break...
If a 1/2"foam and leather really did something, we'd all be wearing leather padded beanies on our heads...
...
Just ride extra careful,.. and hope for the best...
... or,.. take the car...
