As said already by YMM, the same safety issues apply.
Here's some food for thought, drivers of larger and heavier road vehicles are subject to higher expectations that drivers of smaller and lighter road vehicles. But apparently the driver of a railcar (or even a hi-rail vehicle driven on rail) appears to be subject to the same expectations and drivers of longer and heavier trains sharing the same tracks.
Have you read and understood the reports yet? The incidents were caused by human factors, not the vehicles involved.
They are quite long reports, it would take a lot of time and patience to read through them.
All cars in a train have braking force so the difference in braking capabilities between locomotive hauled trains and railcars or multiplet units isn't as much as you might imagine.
I've heard of locomotive-hauled trains taking over a mile to come to a stop. Also, I believe there was a time, back when all trains were steam-hauled, when not all train carriages had brakes, this was the time when block signalling was introduced.
The emergency braking deceleration of EMUs is generally at or less than 1.0 metre per second squared (That of VLocity is 1.12 metres per second squared). Trams, another form of rail vehicle that operate under sight operation in most systems, have emergency brake of about 3.0 metres per second squared.
Is that greater than that of the trains that ran at the time block signalling was introduced, back in the 19the
century? My understanding is that trams operate under sight because they shared the road with manually steered vehicles.
A lot of newer light rail systems around the world do use block signalling on reserved track, these systems are simpler than heavy rail block signalling and may be cheaper too. Even ones to don't have signals at junctions, including crossovers.
Trams and light rail vehicles have track brakes, strangely absent from much heavier trains.
Speaking of road vehicles, even road trains appear to be driven on sight, which can be tempting to attribute to the ability to swerve. If a road vehicle stops or slows down, others behind it in the same lane can often change lanes instead of stopping or reducing speed to avoid the vehicle in front. Rail vehicles can only change tracks at crossovers, elsewhere a rail vehicle has to stop to avoid a stationary train ahead and reduce speed or stop if a rail vehicle ahead is going slower.
