Why bollards up the power to weight by adding a car chassis ?
A carefully constructed Westfield won't weigh much more than the bike... Not sure that it would be inherently safer just because it had four wheels though 
Yes, and 4 wheels means it can go round corners... and, on the Gay issue, you don't need all that leather.
