Nobody “ needs” a luxury car. Why should disabled people not be able to want one the same as non disabled people do?
They use the mobility component of their benefit to lease the car, it’s not free. If they want a car that’s not standard to the scheme they need to pay upfront, a substantial amount for a luxury car. Upfront payments can often be required for adaptations too.
If you don’t think disabled people are entitled to the same choices and opportunities as non disabled people say so. It’s ableism though. Of course years of austerity, governments choosing to cut spending, low wages mean that many of us are struggling to maintain a decent standard of living. That’s not the fault of disabled people. We live in one of the richest countries in the world still. There’s an obscene amount of wealth being hoarded by corporations as well as individuals. Some of that being redistributed would be an option. The benefits bill would be lowered for example if some employers actually paid their workers a decent enough wage that meant it didn’t have to be topped up. Just a thought.
