Technically they can’t implement anything without changing the contract writing, which they are slow at. Those part way through the lease, would have to agree and sign the new contract or have the option of handing the car back penalty free, if they didn’t agree to the new terms!
Motabilty will also likely face backlash for their Drive Smart and intention to force it on those part way through a lease, when there’s nothing in the existing contract to say they should acept one.
For the bigges’t lease company, they aren’t half slack how they go about things.
