I don't see that it would affect you getting onto the midwifery course, though it may be detrimental for being able to cope/stay on the course if you think travel will be an issue. If you're planning on applying to a city university with plenty of public transport links, it'll take time to get to placements, but you'd do it. However, if you're in a more rural spread out area with less transport (like where I am and will be traveling from/to) you may have more of a problem.
