That's a risky trap you've set there as many developing countries have better roads than us. Britain is almost unique in the world for the density of its traffic, the density of the road network and the Atlantic weather, which brings cycles of warm wet weather followed by freezing weather. With the almost complete neglect of gully-cleaning and ditch maintenance, water is running all over the roads and penetrating anywhere the tarmac is not perfectly sealed, freezing and breaking up the road.
I'm in Africa where, in comparatively wealthy countries such as South Africa the major roads are in pretty good shape because highways authorities don't need to spend money maintaining gullies and ditches (African roads generally have a huge ditch to cope with occasional cloudbursts) and the roads are usually warm and dry. It's only in countries like Nigeria where local Government are stealing all the money and road contracts have a 65% "dash" attached that they roll the laterite, roll on 2 inches of tarmac and leave it, so that the first time it gets hot or there's a flood and a big truck turns, the tarmac gets torn up and a huge pothole appears, blocking the traffic at the junction.
Eastern-European countries like Serbia and Hungary have new networks of excellent motorways paid for by the EU, which get very litte traffic and run through open countryside with no disturbance to the surface by utilities, so outside of cities like Belgrade and Budapest the motorways are superb. In the cities though is a very different story for reasons similar to our own.
,as the drains/grates are on a hilly road. If they didn't suck the dead leaves and stuff out then when we have a downpour the rain water could overflow up to my door.
