Suggest best car for 47 yo elder sister to learn driving for the first time.

My elder sister is 47 years old. Due to some circumstances, she now needs to learn driving and commute around 30 km every day (15 km each way) through Bengaluru traffic.

She has never driven any vehicle before, but she is determined to learn. Please suggest the best automatic car for her that would be easy to drive. Also, a Maruti driving school good?
