From dmv.org:

If you are under eighteen, states requiring driver's education from a professional driving school (with behind-the-wheel instruction): CA, DL, HI, ID, IA, KS, LA, MD, MA, MI, MN, MS, MT, NH, NJ, NM (waiver available), NY, NC, OH, PA, SC, TX, UT, VT, WA, WI,

Require the course, but not professional, behind-the-wheel instruction: CT, GA, FL, IL, KY, ME, MO, ND, RI, VA,

Professional instruction not required: AL, AK, AR, CO, IN, NE, NV, OK, OR, SD, TN, WV, WY, DC

So, about half of the country is required to have professional, in-car instruction. Quite common.
