Electric tractors ploughing fields in pre-programmed patterns, no operator required. Electric lorries driving along motorways and trunk roads, modular battery systems in the trailer replaced at the end of each shift, no driver required.
Honestly, people are right to highlight problems, but the solutions are already there - they just need further development. 250 years back it took a week to get a cartload of salt from Northwich to Worsley, so people started building canals, reducing the trip to a couple of days. Then came the railways, which almost overnight destroyed the canal economy. Cyclists got sick and tired of shit roads and began to campaign for better surfaces, which prompted the introduction of tarmacadam-style coatings. 50 years ago our roads were a serious bottleneck to the motorist, so we built a system of motorways. And soon, cars will be driving themselves. They'll be parking themselves too, and organising their own charging while you're doing whatever it is you do.
Remember life before the internet? While studying at college, if I wanted to know something, I had to go to the library and spend hours finding the answer. Now I just ask my phone - I don't even need to pick it up or press any buttons. It just tells me. And that's in less than 20 years.
There are still some really big energy density questions to be answered before you make wholesale changes to things like lorries (and even more so, ships). To be honest, simply replacing ICE with electric alternatives is probably the wrong approach anyway; the return of railways carrying the bulk of freight may make a lot more sense in an electric world (I don't know if this is true by the way, but offering electric transport that can be powered directly would seem to be more efficient than lugging batteries around if you don't need to). Someone needs to be crunching some numbers on this stuff, because to get say, a workable rail network carrying the bulk of freight by 2040, you'd need to be starting the capital investment now; the planning process alone can take decades (and this is a key difference between now and your historic examples; back then it was easier to get things done politically).
The ship thing is a real issue; other than nuclear, there simply isn't an alternative to diesel right now, and it may be you can't get rid of diesel for the foreseeable future but introduce partial electric power for in-shore/port operations (I read somewhere that just one bulk carrier ship in somewhere like Portsmouth pumps out more CO2 and N0x than all the vehicles in the city combined). I think some high end yachts have hybrid drives for this purpose.
