Not sure if you get it lost income means some will be unable to afford there car as there carer drives it for them and not only that some who work under PIP if they lose care will be unable to get to work due to no carer. This cut will to PIP under the having to have 4 points even some severe disabilities will lose income as some disabled as said who have carers if they only get mobility and lose over £400 a month or more it does take much sense to work out why would you need a mobility car unless you have enough income to afford to lose that amount of money.
You are quite right in what you are saying.
If you lose the Daily Living it means you cannot recieve the care allowance (if you live on your own) or if someone cares for you…which also knocks onto the pension credit criteria…its a big hit in the pocket.
