When I was a kid, one of the schools I attended had these lines running through the parking lot and part of the athletic fields (out past the end zone). Generations of children attended that school, with no negative effects that I'm aware of.

There were a couple of interesting phenomena, though:

1. On rainy or really humid days, the lines would crackle incessantly (they always hummed a bit). Kind of freaky to hear if you weren't used to it, but it was something that you quickly became accustomed to.

2. Under the right conditions, cars parked under or even near the lines would develop a kind of "static electricity" feel to them, due to an induced electrical current. This was erratic, though, where one person might feel it but the next one might not (it may have depended a lot on what kind of shoes they were wearing and so on) and required a gentle, back-of-the-fingers touch against the metal in order to feel it. It was a very weird sensation if you didn't know to expect it. As far as I know, though, there were no real negative consequences to this - for the people or the cars.
