Irish here as well OP. We live rurally, and in some respects, like playing out until dark, it's very safe.
But the rural roads are too dangerous without a hard shoulder or path for teens to cycle - even if you plaster them head to toe in flashing lights and high-vis. It's just not done in our locality. It's a shame, if there were safe cycle lanes, DS would love to cycle to school (about 6km from the house) and back with his friends.
During the summer you've got agricultural machinery bombing down the road often driven by a 16yo at speed thinking he's in the Fast and the Furious 🙄and in the winter it's too dark with no street lights to walk or cycle.
There's a school bus. One trip to and one trip back from school. No other public transport option. A fuck up by Bus Eireann in Sept 2022 meant that loads of people who didn't need tickets got them "just in case" and left the ones who depend on a bus fucked for a few months at the beginning of the school year. And if he misses the only bus that evening? fuck all good if I'm 50km away at the office. It's not like the bigger towns where there will be another bus along in a half hour.
DS is 11. He could get off the bus at the top of the road, and let himself in during term time, but Tusla recommend that under 14s don't spend extended time alone at home, so that's a pain for the summer. I've also got a neighbour who would report you for anything, so they would be on the phone to Tusla the first week. And I'm rather too busy to have to sit through a malicious SS assessment.
If I worked locally and could be there in 20 mins in any emergency it might be different but my commute is 90 mins one way. Myself and another mum have dovetailed our WFH days for the summer and if it goes well, we might keep it going next year too. It means that he's got company too for the summer.
