Unroadworthy Uber cars

I have been travelling with uber comfort for a few years. Recently the cars have deteriorated. They are old and bashed up. These rebuild Corolla’s used to be on Uber x. Three cars are not even roadworthy. The tyres are in a terrible condition. Somebody is being paid to get these vehicles onto the platform *******ly. We are being duped into paying extra for uber comfort whilst getting picked up in these cars.
