Why do manual cars not use a sequential change?

Probably because it's simpler and cheaper to use the usual gated arrangement where the driver has to select gears, literally, manually.
The sequential selector system requires additional mechanical complexity.

can it be that more complex? bike's have been using it for years

If you think about the mechanical arrangement of a typical 5 speed box you have a mainshaft and a lay shaft. Each get is the result of a pair of cogs meshing
Bike boxes use dog clutches to engage gears rather than a mechanical gate as such. They're very different to car boxes. They components are smaller as bikes are lighter and the engines are not delivering nearly as much torque.
Modern sequential shifts use conventional car gearboxes with electro-hydraulic actuators. The same type of actuator takes over the clutch operation.
It's therefore quite simple to make a fully automatic mode available if the driver wants to use it just by embedding some extra code in to the ECU.
The VW DSG is interesting.

Anyone tried the DSG on a SEAT, very quick!

Chris Green can tell you all about those.
