See the attached screenshot: city cars treat themselves as being far longer than they really are: this makes it difficult to manage congestion effectively. This does not apply to players' vehicles.
Tested with Standard R 3302 in Windows, 32-bit.

Cars take at least one tile, iirc. This should happen with different player convois too. Afaik, nothing has changed with the citycar code.
Dwachs,
the player vehicles get much closer to each other than the cars do; and cars didn't used to stay this far apart.
I don't agree with James, my buses aren't more than one behind each other on each tile. Maybe it's just a feeling because your citycars here are very small.
With player vehicles, the space that they leave is dependant on their actual length: with city cars, they all leave a very large amount of space whether they need to do so or not.
James - you mean, as if the cars had all length of 16?
@James: your claim is not true. Just test it with the short road vehicles in pak128.Britain.
I would consider this as intended (or at least as implemented) behavior. This thread is then an extension request rather than a bug report ;)
James, since you have the sourcecode your should at least look at the relevant part before posting. The routine in question are called ist_weg_frei() and will block further driving, if on the next tile is any vehicle regardless of its length. (Actually, since the check is somewhat expensive, it is only done when entering a new tiel, thus it is simply not possible at the moment to stop in the middle of a tile). This is true for both, citycars and convoys.
