Q. Referring back to the previous question (2496), davening before neitz standing versus sitting in the car after neitz. If there would be no difference in kavana, what would be the better option? 
A. Horav Shlomo Miller’s Shlit’a opinion is that is better to daven before the neitz standing than on the proper time seating in a car, even if the kavana remains similar.
