3. Perceived behavioral control
The third DTPB component, perceived behavioral control, decomposed in perceived ability and external source
constraints was discussed most profoundly. The awareness of the incomplete infrastructure is a big drawback.
‘There are not enough opportunities to charge batteries.’ ‘The charging of batteries will take so much effort and
time.’ ‘The system will be too expensive.’ ‘Switching my batteries would be as switching my petrol container,
It’s a part of my car!’ ‘Will it be cheaper or more expensive after all? ’Not everyone has access to his own place
for charging batteries;’ ‘Is it safe, when you crash and the car catches fire?’ Anticipated policy measures were
discussed as well. ‘In the beginning the policies will support us, but afterwards they will charge us for using our
home made energy.’ The charging itself is perceived as very easy to do: ‘just plug and play!’ Before the try-out they all perceived their own skills of driving the car as very competitive. After the simulation test, their self
confidence was much lower on this matter
