<prompt> Human: I used to drive 5 miles to the train each day so gas mileage was not a concern. I also just had a baby so I needed a bigger car. I went out and bought a big safe SUV with all the bells and whistles Acura mdx. Three months ago I switched jobs and now drive about 70 miles each day. The mdx needs premium gas and Im spending about 250 a month. Regardless of what I do my wifes lease ends in February and we will need to get a new car. She only drives 20 miles a day. My options are do I give her the mdx and get something fuel efficient or do the gas savings really never amount to much in which case I will just lease her another car. Im debating between a hybrid, phev, or fully electric. I was considering a model 3 but dont think you get enough bang for your buck. Also am dreading going to small car from suv.  <response>: Do the math. hint: it doesnt
