drivers well and consider it helpful. However, many of them prefer to receive
warnings right in time when they approach a dangerous location. A feature that
RDS/TMC cannot offer for technical reasons. The majority of the test users was
experienced with navigation systems. A share of 56% considers a vehicle
communication system very reasonable, 32% think that it is partly reasonable. In
general a positive safety impact and improvements in traffic flow are expected.

Figure 48: Expectations versus experience
Figure 48 shows that positive experience after driving is in general exceeding the
positive expectations the test subjects had before. The accumulated judgements
“very positive” and “rather positive” are beyond 50%. Only the judgement on “limited
access” is lower. This could be due to the fact that this use case was not
understood as well as the others. Most of the test subjects think that C2X
communication should be standard equipment. The high percentage before again
increased after driving with the systems. Figure 49 shows this result.
