Taxi companies, Uber, couriers, black cabs - none of these pay business rates and all use parking spaces. "Southwark are also going to market again for their car sharing relationship. This would add extra pressure to insure against the loss of this relationship by Zipcar. " I suspect Southwark have granted them temporary rights until they go 'to market'. He is suggesting that by giving them rights of use NOW it has increased the pressure on Zipcar to remain (presumably either by through the sunk cost of becoming active there, or by proving the value of Flex to themselves). I do not think he has suggested Avis will continue to have rights should they fail to come to an arrangement with Southwark.
