Hatchback?
Australia?
Crikey!
Get a Audi S3 or A3 Sportback, and your mom AND you will jump for joy, higher than a Wallaby!
When your mom isn't driving the car... wink wink, you drive it.
Hatchback, check
AEB, check
Audi Magnetic Ride, check (for comfy, but aggressive driving)
Audi Side Assist and Audi Active Lane Assist, check
Or, lucky Aussies get the A3 E-tron Sportback:
2016 Audi A3 Sportback e-tron pricing and specifications
Which just came out in Australia.
Good luck in any case.
