Where I live in the UK the issue is rarely a single piece of litter. It's things like lay-bys or roadsides strewn with thousands of pieces of litter (and human faeces, used sanitary/contraceptive products etc). The logistics industry is the biggest offender: lay-bys are used as ad-hoc lorry parks and the local council would have to send out a team several times a week to keep them clean (they do clear them every now and again when enough people complain, but it never takes long for the mess to return since HGVs are parked in these lay-bys 20+ hours a day). They claim to be unable to afford to do this, and seem unwilling to demand that the companies responsible clean up their act.

The second biggest issue is verges and field gates full of old tyres, rubble, old appliances, asbestos and other rubbish that has been dumped. This has been exacerbated recently by the council only opening their waste disposal sites a few days a week, and charging to dispose of most things.
