Safe for a 10month old in convertible carseat?

My hubby just bought a Jeep Wrangler and we have the bikini top on it now. My question is, it it safe? She is in a rear facing convertible carseat. For short trips of course. Nothing over 40 miles or lower with the bikini top on it. Because the wind in her face. He would put the soft top on if we went on a further trip and needed to drive over 40 mph. Would this be ok for short grocery pr just driving around in good weather or no?
