thanks folks:
1. Avoiding being knocked off bike = leave my home town of London - not an option.
2. Not wearing a helmet on urban flats. Well that's also something i've done all my life to date. However, now i'm in my mid-50s, bashing the head in any type of collision comes with risk of greater consequences. I'm inclined to think that it's wise to wear a helmet if you're over 50 in London.
3. Basket case - I can see the attraction of using a helmet as a basket. Correction tho - a folding helmet can also be used as a basket AND has the added feature of being folded away.
I've located samples to view:
The Overade Plixi is available at
Condor Cycles in Greys Inn Rd, London.

The Hedkayse is sold by Push in Newington Grn but samples are held at Brompton: Covent Garden/ Westfield.

The FEND and Diamond and Park are both NYC based so viewing isn't an option. I'll let you know how i got on.
