Is there adequate lighting to define the different levels between the driveway and the garden area? If not, that could be a safety issue, someone may not see the different levels in the dark and could fall and injure themselves. Could a car get “stuck” in the garden area when attempting to drive/back out of the garage? Car stuck in driveway blocking access to all other vehicles – could pose a safety issue for residents with medical issues? Of course a car could block any driveway at anytime for any number of reasons. But when you have a factor that may increase the chances of this happening – then perhaps you have an issue to for your EC to address.
If it was me I would point out all the safety related issues you can find with this rather than ask them to ”redesign”. When anyone hears the word “design” they think chintz cushions and tie back curtains – therefore not worthy of immediate consideration. But when they see the word safety they should really take note and look into the issue.
