The "War on Terror" is over. Terrorism is basically just another form of crime really - and not a very common one. Even during 2001 - 9/11 killed what, 3,000 people? Regular old homicide was ~14,000. And that's the most people they ever killed, whereas the US homicide rate is a yearly occurrence.
So I'm sure there will still be the occasional car attack, and of course intercepting cells and hunting down the wannabe terrorists is still important. But it's just part of the background noise of crime.
There are certainly some trends though. Now that they're desperate, out of resources and their cells are shut down or heavily monitored, organised attacks are rarer. Most of the "terrorist attacks" we've seen lately have been repeat offender low level criminals, typically with a history of drug abuse, who snap and commit an attack with questionable links to any greater organisation. The attacks are opportunistic, eg car rammings rather than anything planned out and well equipped.
And yes, far right violence is definitely an increasing concern.
Looking back over the history of terrorist attacks in Europe, Islamic attacks were sporadic and nowhere near the level of earlier periods like the 70s, 80s and early 90s.

This is raw numbers, not even adjusting for population growth which would make the trend even more stark.
Basically, the IRA, ETA and a few others killed way more people in Europe than Islamic terrorism ever did, even if you include the outliers like Madrid, London and Paris.
Our parents and grandparents lived through an era of far worse terrorism in Europe than we have.
But Islamic terrorist attacks are a big problem... in the Middle East:
